Philadelphia is the economic and cultural anchor of the Delaware Valley , located along the lower Delaware and Schuylkill Rivers , within the Northeast megalopolis . The Delaware Valley 's population of 7.2 million ranks it as the eighth - largest combined statistical area in the United States . William Penn , an English Quaker , founded the city in 1682 to serve as capital of the Pennsylvania Colony . Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States , who signed the Declaration of Independence in 1776 at the Second Continental Congress , and the Constitution at the Philadelphia Convention of 1787 . Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress , the preservation of the Liberty Bell , the Battle of Germantown , and the Siege of Fort Mifflin . Philadelphia was one of the nation 's capitals during the revolution , and served as temporary U.S. capital while Washington , D.C. , was under construction . In the 19th century , Philadelphia became a major industrial center and a railroad hub . The city grew from an influx of European immigrants , most of whom came from Ireland , Italy and Germany -- the three largest reported ancestry groups in the city as of 2015 . In the early 20th century , Philadelphia became a prime destination for African Americans during the Great Migration after the Civil War , as well as Puerto Ricans . The city 's population doubled from one million to two million people between 1890 and 1950 . The Philadelphia area 's many universities and colleges make it a top study destination , as the city has evolved into an educational and economic hub . According to the Bureau of Economic Analysis , the Philadelphia area had a gross domestic product of US $431 billion in 2016 , the eighth - largest metropolitan economy in the United States . Philadelphia is the center of economic activity in Pennsylvania and is home to five Fortune 1000 companies . The Philadelphia skyline is expanding , with a market of almost 81,900 commercial properties in 2016 , including several nationally prominent skyscrapers . Philadelphia has more outdoor sculptures and murals than any other American city . Fairmount Park , when combined with the adjacent Wissahickon Valley Park in the same watershed , is one of the largest contiguous urban park areas in the United States . The city is known for its arts , culture , and colonial history which attracted 42 million domestic tourists in 2016 who spent $6.8 billion , generating an estimated $11 billion in total economic impact in the city and surrounding four counties of Pennsylvania . Philadelphia has also emerged as a biotechnology hub . Philadelphia is the birthplace of the United States Marine Corps , and is also the home of many U.S. firsts , including the first library ( 1731 ) , hospital ( 1751 ) , medical school ( 1765 ) , national capital ( 1774 ) , stock exchange ( 1790 ) , zoo ( 1874 ) , and business school ( 1881 ) . Philadelphia contains 67 National Historic Landmarks and the World Heritage Site of Independence Hall . The city became a member of the Organization of World Heritage Cities in 2015 , as the first World Heritage City in the United States .

The Lenape are a Native American tribe and First Nations band government . They are also called Delaware Indians , and their historical territory was along the Delaware River watershed , western Long Island , and the Lower Hudson Valley . Most Lenape were pushed out of their Delaware homeland during the 18th century by expanding European colonies , exacerbated by losses from intertribal conflicts . Lenape communities were weakened by newly introduced diseases , mainly smallpox , and violent conflict with Europeans . Iroquois people occasionally fought the Lenape . Surviving Lenape moved west into the upper Ohio River basin . The American Revolutionary War and United States ' independence pushed them further west . In the 1860s , the United States government sent most Lenape remaining in the eastern United States to the Indian Territory ( present - day Oklahoma and surrounding territory ) under the Indian removal policy . In the 21st century , most Lenape reside in Oklahoma , with some communities living also in Wisconsin , Ontario ( Canada ) and their traditional homelands . Europeans came to the Delaware Valley in the early 17th century , with the first settlements founded by the Dutch , who in 1623 built Fort Nassau on the Delaware River opposite the Schuylkill River in what is now Brooklawn , New Jersey . The Dutch considered the entire Delaware River valley to be part of their New Netherland colony . In 1638 , Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina ( present - day Wilmington , Delaware ) and quickly spread out in the valley . In 1644 , New Sweden supported the Susquehannocks in their military defeat of the English colony of Maryland . In 1648 , the Dutch built Fort Beversreede on the west bank of the Delaware , south of the Schuylkill near the present - day Eastwick neighborhood , to reassert their dominion over the area . The Swedes responded by building Fort Nya Korsholm , or New Korsholm , after a town in Finland with a Swedish majority . In 1655 , a Dutch military campaign led by New Netherland Director - General Peter Stuyvesant took control of the Swedish colony , ending its claim to independence . The Swedish and Finnish settlers continued to have their own militia , religion , and court , and to enjoy substantial autonomy under the Dutch . The English conquered the New Netherland colony in 1664 , though the situation did not change substantially until 1682 when the area was included in William Penn 's charter for Pennsylvania . In 1681 , in partial repayment of a debt , Charles II of England granted Penn a charter for what would become the Pennsylvania colony . Despite the royal charter , Penn bought the land from the local Lenape to be on good terms with the Native Americans and ensure peace for his colony . Penn made a treaty of friendship with Lenape chief Tammany under an elm tree at Shackamaxon , in what is now the city 's Fishtown neighborhood . Penn named the city Philadelphia , which is Greek for brotherly love , derived from the Ancient Greek terms φίλος phílos ( beloved , dear ) and ἀδελφός adelphós ( brother , brotherly ) . As a Quaker , Penn had experienced religious persecution and wanted his colony to be a place where anyone could worship freely . This tolerance , far more than afforded by most other colonies , led to better relations with the local native tribes and fostered Philadelphia 's rapid growth into America 's most important city . Benjamin Franklin , 1777 Penn planned a city on the Delaware River to serve as a port and place for government . Hoping that Philadelphia would become more like an English rural town instead of a city , Penn laid out roads on a grid plan to keep houses and businesses spread far apart , with areas for gardens and orchards . The city 's inhabitants did not follow Penn 's plans , however , as they crowded by the Delaware River port , and subdivided and resold their lots . Before Penn left Philadelphia for the last time , he issued the Charter of 1701 establishing it as a city . Though poor at first , the city became an important trading center with tolerable living conditions by the 1750s . Benjamin Franklin , a leading citizen , helped improve city services and founded new ones , such as fire protection , a library , and one of the American colonies ' first hospitals . A number of philosophical societies were formed , which were centers of the city 's intellectual life : the Philadelphia Society for Promoting Agriculture ( 1785 ) , the Pennsylvania Society for the Encouragement of Manufactures and the Useful Arts ( 1787 ) , the Academy of Natural Sciences ( 1812 ) , and the Franklin Institute ( 1824 ) . These societies developed and financed new industries , attracting skilled and knowledgeable immigrants from Europe . Philadelphia 's importance and central location in the colonies made it a natural center for America 's revolutionaries . By the 1750s , Philadelphia had surpassed Boston to become the largest city and busiest port in British America , and second in the British Empire after London . The city hosted the First Continental Congress ( 1774 ) before the Revolutionary War ; the Second Continental Congress ( 1775 -- 76 ) , which signed the United States Declaration of Independence , during the war ; and the Constitutional Convention ( 1787 ) after the war . Several battles were fought in and near Philadelphia as well . President 's House -- the presidential mansion of George Washington and John Adams , 1790 -- 1800 Philadelphia served as the temporary capital of the United States while the new capital was under construction in the District of Columbia from 1790 to 1800 . In 1793 , the largest yellow fever epidemic in U.S. history killed approximately 4,000 to 5,000 people in Philadelphia , or about 10 % of the city 's population . The state capital was moved to Lancaster in 1799 , then Harrisburg in 1812 , while the federal government was moved to Washington , D.C. in 1800 upon completion of the White House and U.S. Capitol building . The city remained the young nation 's largest until the late 18th century , being both a financial and a cultural center for America . In 1816 , the city 's free black community founded the African Methodist Episcopal Church ( AME ) , the first independent black denomination in the country , and the first black Episcopal Church . The free black community also established many schools for its children , with the help of Quakers . New York City surpassed Philadelphia in population by 1790 . Large - scale construction projects for new roads , canals , and railroads made Philadelphia the first major industrial city in the United States . Throughout the 19th century , Philadelphia hosted a variety of industries and businesses , the largest being textiles . Major corporations in the 19th and early 20th centuries included the Baldwin Locomotive Works , William Cramp & Sons Shipbuilding Company , and the Pennsylvania Railroad . Industry , along with the U.S. Centennial , was celebrated in 1876 with the Centennial Exposition , the first official World 's Fair in the United States . Immigrants , mostly from Ireland and Germany , settled in Philadelphia and the surrounding districts . These immigrants were largely responsible for the first general strike in North America in 1835 , in which workers in the city won the ten - hour workday . The city was a destination for thousands of Irish immigrants fleeing the Great Famine in the 1840s ; housing for them was developed south of South Street and later occupied by succeeding immigrants . They established a network of Catholic churches and schools and dominated the Catholic clergy for decades . Anti-Irish , anti-Catholic nativist riots erupted in Philadelphia in 1844 . The rise in population of the surrounding districts helped lead to the Act of Consolidation of 1854 , which extended the city limits from the 2 square miles ( 5.2 km ) of Center City to the roughly 134 square miles ( 350 km ) of Philadelphia County . In the latter half of the century , immigrants from Russia , Eastern Europe and Italy , and African Americans from the southern U.S. settled in the city . Philadelphia was represented by the Washington Grays in the American Civil War . The African - American population of Philadelphia increased from 31,699 to 219,559 between 1880 and 1930 . Twentieth - century black newcomers were part of the Great Migration out of the rural south to northern and midwestern industrial cities .

Opening day ceremonies at the Centennial Exhibition at Memorial Hall , 1876 - first World 's Fair in the United States By the 20th century , Philadelphia had become known as `` corrupt and contented '' , with an entrenched Republican political machine and a complacent population . The first major reform came in 1917 when outrage over the election - year murder of a police officer led to the shrinking of the City Council from two houses to just one . In July 1919 , Philadelphia was one of more than 36 industrial cities nationally to suffer a race riot of ethnic whites against blacks during Red Summer , in post-World War I unrest , as recent immigrants competed with blacks for jobs . In the 1920s , the public flouting of Prohibition laws , organized crime , mob violence , and police involvement in illegal activities led to the appointment of Brig. Gen. Smedley Butler of the U.S. Marine Corps as director of public safety , but political pressure prevented any long - term success in fighting crime and corruption . In 1940 , non-Hispanic whites constituted 86.8 % of the city 's population . The population peaked at more than two million residents in 1950 , then began to decline with the restructuring of industry , which led to the loss of many middle - class union jobs . In addition , suburbanization had enticed many of the more affluent residents to outlying railroad commuting towns and newer housing . The resulting reduction in Philadelphia 's tax base and the resources of local government caused the city to struggle through a long period of adjustment , with it approaching bankruptcy by the late 1980s . Revitalization and gentrification of neighborhoods began in the late 1970s and continues into the 21st century , with much of the development occurring in the Center City and University City neighborhoods . After many of the old manufacturers and businesses left Philadelphia or shut down , the city started attracting service businesses and began to market itself more aggressively as a tourist destination . Glass - and - granite skyscrapers were built in Center City beginning in the 1980s . Historic areas such as Old City and Society Hill were renovated during the reformist mayoral era of the 1950s through the 1980s , making those areas among the most desirable neighborhoods in Center City . These developments have begun a reversal of the city 's population decline between 1950 and 2000 during which it lost about one - quarter of its residents . The city eventually began experiencing a growth in its population in 2007 , which has continued with gradual yearly increases to the present . Geography Landsat simulated - color image of Philadelphia and the Delaware River Topography The geographic center of Philadelphia is located approximately at 40 ° 0 ′ 34 '' north latitude and 75 ° 8 ′ 0 '' west longitude . The 40th parallel north passes through neighborhoods in Northeast Philadelphia , North Philadelphia , and West Philadelphia including Fairmount Park . The city encompasses 142.71 square miles ( 369.62 km ) , of which 134.18 square miles ( 347.52 km ) is land and 8.53 square miles ( 22.09 km ) , or 6 % , is water . Natural bodies of water include the Delaware and Schuylkill rivers , the lakes in Franklin Delano Roosevelt Park , and Cobbs , Wissahickon , and Pennypack creeks . The largest artificial body of water is the East Park Reservoir in Fairmount Park . The lowest point is 10 feet ( 3 m ) above sea level , while the highest point is in Chestnut Hill , about 445 feet ( 136 m ) above sea level near the intersection of Germantown Avenue and Bethlehem Pike . Philadelphia is situated on the Fall Line that separates the Atlantic coastal plain from the Piedmont . The rapids on the Schuylkill River at East Falls were inundated by the completion of the dam at the Fairmount Water Works . The city is the seat of its own county . The adjacent counties are Montgomery to the northwest ; Bucks to the north and northeast ; Burlington County , New Jersey , to the east ; Camden County , New Jersey , to the southeast ; Gloucester County , New Jersey , to the south ; and Delaware County to the southwest .

Center City is structured with long straight streets running nearly due east - west and north - south , forming a grid pattern between the Delaware and Schuylkill rivers that is aligned with their courses . The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire . Penn planned the creation of five public parks in the city which were renamed in 1824 ( new names in parenthesis ) : Centre Square ( Penn Square ) , Northeast Square ( Franklin Square ) , Southeast Square ( Washington Square ) , Southwest Square ( Rittenhouse Square ) , and Northwest Square ( Logan Circle / Square ) . Center City had an estimated 183,240 residents as of 2015 , making it the second-most populated downtown area in the United States , after Midtown Manhattan in New York City . Philadelphia 's neighborhoods are divided into large sections -- North , Northeast , South , Southwest Philadelphia , West , and Northwest -- surrounding Center City , which corresponds closely with the city 's limits before consolidation in 1854 . Each of these large areas contains numerous neighborhoods , some of whose boundaries derive from the boroughs , townships , and other communities that constituted Philadelphia County before their inclusion within the city . The City Planning Commission , tasked with guiding growth and development of the city , has divided the city into 18 planning districts as part of the Philadelphia2035 physical development plan . Much of the city 's 1980 zoning code was overhauled from 2007 to 2012 as part of a joint effort between former mayors John F. Street and Michael Nutter . The zoning changes were intended to rectify incorrect zoning maps in order to facilitate future community development , as the city forecasts an additional 100,000 residents and 40,000 jobs will be added by 2035 . The Philadelphia Housing Authority is the largest landlord in Pennsylvania . Established in 1937 , it is the nation 's fourth - largest housing authority , housing about 84,000 people and employing 1,250 . In 2013 , its budget was $371 million . The Philadelphia Parking Authority works to ensure adequate parking for city residents , businesses and visitors . Architecture Main articles : Architecture of Philadelphia and List of tallest buildings in Philadelphia Juxtaposition of architectural styles in Center City , showing One Liberty Place and City Hall Philadelphia 's architectural history dates back to colonial times and includes a wide range of styles . The earliest structures were constructed with logs , but brick structures were common by 1700 . During the 18th century , the cityscape was dominated by Georgian architecture , including Independence Hall and Christ Church . In the first decades of the 19th century , Federal and Greek Revival architecture were the dominant styles produced by Philadelphia architects such as Benjamin Latrobe , William Strickland , John Haviland , John Notman , Thomas Walter , and Samuel Sloan . Frank Furness is considered Philadelphia 's greatest architect of the second half of the 19th century . His contemporaries included John McArthur Jr. , Addison Hutton , Wilson Eyre , the Wilson Brothers , and Horace Trumbauer . In 1871 , construction began on the Second Empire - style Philadelphia City Hall . The Philadelphia Historical Commission was created in 1955 to preserve the cultural and architectural history of the city . The commission maintains the Philadelphia Register of Historic Places , adding historic buildings , structures , sites , objects and districts as it sees fit . In 1932 , Philadelphia became home to the first modern International Style skyscraper in the United States , the PSFS Building , designed by George Howe and William Lescaze . The 548 ft ( 167 m ) City Hall remained the tallest building in the city until 1987 when One Liberty Place was completed . Numerous glass and granite skyscrapers were built in Center City beginning in the late 1980s . In 2007 , the Comcast Center surpassed One Liberty Place to become the city 's tallest building . The Comcast Technology Center is under construction in Center City with an expected completion in 2018 . The new tower will reach a height of 1,121 ft ( 342 m ) , and will be the tallest building in the United States outside of Manhattan and Chicago . For much of Philadelphia 's history , the typical home has been the row house . The row house was introduced to the United States via Philadelphia in the early 19th century and , for a time , row houses built elsewhere in the United States were known as `` Philadelphia rows '' . A variety of row houses are found throughout the city , from Federal - style continuous blocks in Old City and Society Hill to Victorian - style homes in North Philadelphia to twin row houses in West Philadelphia . While newer homes have been built recently , much of the housing dates to the 18th , 19th and early 20th centuries , which has created problems such as urban decay and vacant lots . Some neighborhoods , including Northern Liberties and Society Hill , have been rehabilitated through gentrification .

The two main streets were named Broad Street ( the north - south artery , since designated Pennsylvania Route 611 ) and High Street ( the east - west artery , since renamed Market Street ) converging at Centre Square which later became the site of City Hall . Traffic heading into Philadelphia on Interstate 95 during the morning rush hour . Interstate 95 ( the Delaware Expressway ) traverses the southern and eastern edges of the city along the Delaware River as the main north - south controlled - access highway . The city is also served by Interstate 76 ( the Schuylkill Expressway ) which runs along the Schuylkill River , intersecting the Pennsylvania Turnpike at King of Prussia and providing access to Harrisburg and points west . Interstate 676 ( the Vine Street Expressway ) links I - 95 and I - 76 through Center City by running below street level between the eastbound and westbound lanes of Vine Street . Entrance and exit ramps for the Benjamin Franklin Bridge are near the eastern end of the expressway , just west of the I - 95 interchange . The Roosevelt Boulevard and Expressway ( U.S. 1 ) connect Northeast Philadelphia with Center City via I - 76 through Fairmount Park . Woodhaven Road ( Route 63 ) and Cottman Avenue ( Route 73 ) serve the neighborhoods of Northeast Philadelphia , running between I - 95 and the Roosevelt Boulevard . The Fort Washington Expressway ( Route 309 ) extends north from the city 's northern border , serving Montgomery County and Bucks County . U.S. Route 30 ( Lancaster Avenue ) extends westward from West Philadelphia to Lancaster . Ben Franklin Bridge at sunrise Interstate 476 ( locally referred to as the Blue Route ) traverses Delaware County , bypassing the city to the west and serving the city 's western suburbs , as well as providing a link to Allentown and points north . Interstate 276 ( the Pennsylvania Turnpike 's Delaware River extension ) acts as a bypass and commuter route to the north of the city as well as a link to the New Jersey Turnpike and New York City . The Delaware River Port Authority operates four bridges in the Philadelphia area across the Delaware River to New Jersey : the Walt Whitman Bridge ( I - 76 ) , the Benjamin Franklin Bridge ( I - 676 and U.S. 30 ) , the Betsy Ross Bridge ( New Jersey Route 90 ) , and the Commodore Barry Bridge ( U.S. 322 in Delaware County , south of the city ) .

Rail Main article : History of rail transport in Philadelphia Suburban Station with Art Deco architecture Since the early days of rail transportation in the United States , Philadelphia has served as a hub for several major rail companies , particularly the Pennsylvania Railroad and the Reading Railroad . The Pennsylvania Railroad first operated Broad Street Station , then 30th Street Station and Suburban Station , and the Reading Railroad operated Reading Terminal , now part of the Pennsylvania Convention Center . The two companies also operated competing commuter rail systems in the area . The two systems now operate as a single system under the control of SEPTA , the regional transit authority . Additionally , the PATCO Speedline subway system and NJ Transit 's Atlantic City Line operate successor services to southern New Jersey . In 1911 , Philadelphia had nearly 4,000 electric trolleys running on 86 lines . In 2005 , SEPTA reintroduced trolley service to the Girard Avenue Line , Route 15 . SEPTA operates six `` subway - surface '' trolleys that run on street - level tracks in West Philadelphia and subway tunnels in Center City , along with two surface trolleys in adjacent suburbs . Philadelphia is a regional hub of the federally owned Amtrak system , with 30th Street Station being a primary stop on the Washington - Boston Northeast Corridor and the Keystone Corridor to Harrisburg and Pittsburgh . 30th Street also serves as a major station for services via the Pennsylvania Railroad 's former Pennsylvania Main Line to Chicago . As of 2017 , 30th Street is Amtrak 's third - busiest station in the country , after New York City and Washington . Walk Score ranks A 2017 study by Walk Score ranked Philadelphia the fifth most walkable major city in the United States with a score of 79 out of 100 , in the middle of the `` very walkable '' range . The city was just edged out by fourth place Miami ( 79.2 ) , with the top three cities being New York , San Francisco , and Boston . Philadelphia placed fifth in the public transit friendly category , behind Washington , D.C. , with the same three cities for walkability topping this category . The city ranked tenth in the bike friendly cities category , with the top three cities being Minneapolis , San Francisco and Portland . The readers of USA Today newspaper voted the Schuylkill River Trail the best urban trail in the nation in 2015 . Utilities Fairmount Water Works , Philadelphia 's second municipal waterworks In 1815 , Philadelphia began sourcing its water via the Fairmount Water Works located on the Schuylkill River , the nation 's first major urban water supply system . In 1909 , the Water Works was decommissioned as the city transitioned to modern sand filtration methods . Today , the Philadelphia Water Department ( PWD ) provides drinking water , wastewater collection , and stormwater services for Philadelphia , as well as surrounding counties . PWD draws about 57 percent of its drinking water from the Delaware River and the balance from the Schuylkill River . The city has two filtration plants on the Schuylkill River and one on the Delaware River . The three plants can treat up to 546 million gallons of water per day , while the total storage capacity of the combined plant and distribution system exceeds one billion gallons . The wastewater system consists of three water pollution control plants , 21 pumping stations , and about 3,657 miles ( 5,885 km ) of sewers . Exelon subsidiary PECO Energy Company , founded as the Brush Electric Light Company of Philadelphia in 1881 and renamed Philadelphia Electric Company ( PECO ) in 1902 , provides electricity to about 1.6 million customers and more than 500,000 natural gas customers in the southeastern Pennsylvania area including the city of Philadelphia and most of its suburbs . PECO is the largest electric and natural gas utility in the state with 472 power substations and nearly 23,000 miles ( 37,000 km ) of electric transmission and distribution lines , along with 12,000 miles ( 19,000 km ) of natural gas transmission , distribution & service lines . Philadelphia Gas Works ( PGW ) , overseen by the Pennsylvania Public Utility Commission , is the nation 's largest municipally - owned natural gas utility . PGW serves over 500,000 homes and businesses in the Philadelphia area . Founded in 1836 , the company came under city ownership in 1987 and has been providing the majority of gas distributed within city limits . In 2014 , the City Council refused to conduct hearings on a $1.86 billion sale of PGW , part of a two - year effort that was proposed by the mayor . The refusal led to the prospective buyer terminating its offer . Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the Bell System went into effect . The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created , with the city and its northern suburbs retaining 215 . Overlay area code 267 was added to the 215 service area in 1997 , and 484 was added to the 610 area in 1999 . A plan in 2001 to introduce a third overlay code to both service areas ( area code 445 to 215 , area code 835 to 610 ) was delayed and later rescinded . In 2005 , a low - cost , citywide Wi - Fi service was approved for installation in the city . Wireless Philadelphia would have been the first municipal internet utility in a large U.S. city , but the plan was abandoned in 2008 as EarthLink pushed back the completion date several times . Mayor Nutter 's administration closed the project in 2009 after an attempt to revitalize it failed .

The park was built to commemorate Philadelphia 's first two sister city relationships , with Tel Aviv and Florence . The Toruń Triangle , honoring the sister city relationship with Toruń , Poland , was constructed in 1976 , west of the United Way building at 18th Street and the Benjamin Franklin Parkway . Sister Cities Park was redesigned and reopened in 2012 , featuring an interactive fountain honoring Philadelphia 's sister and partnership cities , a café and visitor 's center , children 's play area , outdoor garden , and boat pond , as well as a pavilion built to environmentally friendly standards .

These terrains encompass from South to North and then counter-clockwise : the shores from the east - shore mouth of the river and the sea coast to Western Long Island ( all of both colonial New Amsterdam and New Sweden ) , and portions of Western Connecticut up to the latitude of the Massachusetts corner of today 's boundaries -- making the eastern bounds of their influence , thence their region extended : westerly past the region around Albany , NY to the Susquehanna River side of the Catskills , then southerly through the eastern Poconos outside the rival Susquehannock lands past Eastern Pennsylvania then southerly past the site of Colonial Philadelphia past the west bank mouth of the Delaware and extending south from that point along a stretch of sea coast in northern colonial Delaware . The Susquehanna - Delaware watershed divides bound the frequently contested ' hunting grounds ' between the rival Susquehannock peoples and the Lenape peoples , whilst the Catskills and Berkshires played a similar boundary role in the northern regions of their original colonial era range .

Philadelphia is the economic and cultural anchor of the Delaware Valley , located along the lower Delaware and Schuylkill Rivers , within the Northeast megalopolis . The Delaware Valley 's population of 7.2 million ranks it as the eighth - largest combined statistical area in the United States . William Penn , an English Quaker , founded the city in 1682 to serve as capital of the Pennsylvania Colony . Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States , who signed the Declaration of Independence in 1776 at the Second Continental Congress , and the Constitution at the Philadelphia Convention of 1787 . Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress , the preservation of the Liberty Bell , the Battle of Germantown , and the Siege of Fort Mifflin . Philadelphia was one of the nation 's capitals during the revolution , and served as temporary U.S. capital while Washington , D.C. , was under construction . In the 19th century , Philadelphia became a major industrial center and a railroad hub . The city grew from an influx of European immigrants , most of whom came from Ireland , Italy and Germany -- the three largest reported ancestry groups in the city as of 2015 . In the early 20th century , Philadelphia became a prime destination for African Americans during the Great Migration after the Civil War , as well as Puerto Ricans . The city 's population doubled from one million to two million people between 1890 and 1950 . The Philadelphia area 's many universities and colleges make it a top study destination , as the city has evolved into an educational and economic hub . According to the Bureau of Economic Analysis , the Philadelphia area had a gross domestic product of US $431 billion in 2016 , the eighth - largest metropolitan economy in the United States . Philadelphia is the center of economic activity in Pennsylvania and is home to five Fortune 1000 companies . The Philadelphia skyline is expanding , with a market of almost 81,900 commercial properties in 2016 , including several nationally prominent skyscrapers . Philadelphia has more outdoor sculptures and murals than any other American city . Fairmount Park , when combined with the adjacent Wissahickon Valley Park in the same watershed , is one of the largest contiguous urban park areas in the United States . The city is known for its arts , culture , and colonial history which attracted 42 million domestic tourists in 2016 who spent $6.8 billion , generating an estimated $11 billion in total economic impact in the city and surrounding four counties of Pennsylvania . Philadelphia has also emerged as a biotechnology hub . Philadelphia is the birthplace of the United States Marine Corps , and is also the home of many U.S. firsts , including the first library ( 1731 ) , hospital ( 1751 ) , medical school ( 1765 ) , national capital ( 1774 ) , stock exchange ( 1790 ) , zoo ( 1874 ) , and business school ( 1881 ) . Philadelphia contains 67 National Historic Landmarks and the World Heritage Site of Independence Hall . The city became a member of the Organization of World Heritage Cities in 2015 , as the first World Heritage City in the United States . Before Europeans arrived , the Philadelphia area was home to the Lenape ( Delaware ) Indians in the village of Shackamaxon . The Lenape are a Native American tribe and First Nations band government . They are also called Delaware Indians , and their historical territory was along the Delaware River watershed , western Long Island , and the Lower Hudson Valley . Most Lenape were pushed out of their Delaware homeland during the 18th century by expanding European colonies , exacerbated by losses from intertribal conflicts . Lenape communities were weakened by newly introduced diseases , mainly smallpox , and violent conflict with Europeans . Iroquois people occasionally fought the Lenape . Surviving Lenape moved west into the upper Ohio River basin . The American Revolutionary War and United States ' independence pushed them further west . In the 1860s , the United States government sent most Lenape remaining in the eastern United States to the Indian Territory ( present - day Oklahoma and surrounding territory ) under the Indian removal policy . In the 21st century , most Lenape reside in Oklahoma , with some communities living also in Wisconsin , Ontario ( Canada ) and their traditional homelands . Europeans came to the Delaware Valley in the early 17th century , with the first settlements founded by the Dutch , who in 1623 built Fort Nassau on the Delaware River opposite the Schuylkill River in what is now Brooklawn , New Jersey . The Dutch considered the entire Delaware River valley to be part of their New Netherland colony . In 1638 , Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina ( present - day Wilmington , Delaware ) and quickly spread out in the valley . In 1644 , New Sweden supported the Susquehannocks in their military defeat of the English colony of Maryland . In 1648 , the Dutch built Fort Beversreede on the west bank of the Delaware , south of the Schuylkill near the present - day Eastwick neighborhood , to reassert their dominion over the area . The Swedes responded by building Fort Nya Korsholm , or New Korsholm , after a town in Finland with a Swedish majority . In 1655 , a Dutch military campaign led by New Netherland Director - General Peter Stuyvesant took control of the Swedish colony , ending its claim to independence . The Swedish and Finnish settlers continued to have their own militia , religion , and court , and to enjoy substantial autonomy under the Dutch . The English conquered the New Netherland colony in 1664 , though the situation did not change substantially until 1682 when the area was included in William Penn 's charter for Pennsylvania . In 1681 , in partial repayment of a debt , Charles II of England granted Penn a charter for what would become the Pennsylvania colony . Despite the royal charter , Penn bought the land from the local Lenape to be on good terms with the Native Americans and ensure peace for his colony . Penn made a treaty of friendship with Lenape chief Tammany under an elm tree at Shackamaxon , in what is now the city 's Fishtown neighborhood . Penn named the city Philadelphia , which is Greek for brotherly love , derived from the Ancient Greek terms φίλος phílos ( beloved , dear ) and ἀδελφός adelphós ( brother , brotherly ) . As a Quaker , Penn had experienced religious persecution and wanted his colony to be a place where anyone could worship freely . This tolerance , far more than afforded by most other colonies , led to better relations with the local native tribes and fostered Philadelphia 's rapid growth into America 's most important city . Penn planned a city on the Delaware River to serve as a port and place for government . Hoping that Philadelphia would become more like an English rural town instead of a city , Penn laid out roads on a grid plan to keep houses and businesses spread far apart , with areas for gardens and orchards . The city 's inhabitants did not follow Penn 's plans , however , as they crowded by the Delaware River port , and subdivided and resold their lots . Before Penn left Philadelphia for the last time , he issued the Charter of 1701 establishing it as a city . Though poor at first , the city became an important trading center with tolerable living conditions by the 1750s . Benjamin Franklin , a leading citizen , helped improve city services and founded new ones , such as fire protection , a library , and one of the American colonies ' first hospitals . A number of philosophical societies were formed , which were centers of the city 's intellectual life : the Philadelphia Society for Promoting Agriculture ( 1785 ) , the Pennsylvania Society for the Encouragement of Manufactures and the Useful Arts ( 1787 ) , the Academy of Natural Sciences ( 1812 ) , and the Franklin Institute ( 1824 ) . These societies developed and financed new industries , attracting skilled and knowledgeable immigrants from Europe . Philadelphia 's importance and central location in the colonies made it a natural center for America 's revolutionaries . By the 1750s , Philadelphia had surpassed Boston to become the largest city and busiest port in British America , and second in the British Empire after London . The city hosted the First Continental Congress ( 1774 ) before the Revolutionary War ; the Second Continental Congress ( 1775 -- 76 ) , which signed the United States Declaration of Independence , during the war ; and the Constitutional Convention ( 1787 ) after the war . Several battles were fought in and near Philadelphia as well . Philadelphia served as the temporary capital of the United States while the new capital was under construction in the District of Columbia from 1790 to 1800 . In 1793 , the largest yellow fever epidemic in U.S. history killed approximately 4,000 to 5,000 people in Philadelphia , or about 10 % of the city 's population . The state capital was moved to Lancaster in 1799 , then Harrisburg in 1812 , while the federal government was moved to Washington , D.C. in 1800 upon completion of the White House and U.S. Capitol building . The city remained the young nation 's largest until the late 18th century , being both a financial and a cultural center for America . In 1816 , the city 's free black community founded the African Methodist Episcopal Church ( AME ) , the first independent black denomination in the country , and the first black Episcopal Church . The free black community also established many schools for its children , with the help of Quakers . New York City surpassed Philadelphia in population by 1790 . Large - scale construction projects for new roads , canals , and railroads made Philadelphia the first major industrial city in the United States . Throughout the 19th century , Philadelphia hosted a variety of industries and businesses , the largest being textiles . Major corporations in the 19th and early 20th centuries included the Baldwin Locomotive Works , William Cramp & Sons Shipbuilding Company , and the Pennsylvania Railroad . Industry , along with the U.S. Centennial , was celebrated in 1876 with the Centennial Exposition , the first official World 's Fair in the United States . Immigrants , mostly from Ireland and Germany , settled in Philadelphia and the surrounding districts . These immigrants were largely responsible for the first general strike in North America in 1835 , in which workers in the city won the ten - hour workday . The city was a destination for thousands of Irish immigrants fleeing the Great Famine in the 1840s ; housing for them was developed south of South Street and later occupied by succeeding immigrants . They established a network of Catholic churches and schools and dominated the Catholic clergy for decades . Anti-Irish , anti-Catholic nativist riots erupted in Philadelphia in 1844 . The rise in population of the surrounding districts helped lead to the Act of Consolidation of 1854 , which extended the city limits from the 2 square miles ( 5.2 km ) of Center City to the roughly 134 square miles ( 350 km ) of Philadelphia County . In the latter half of the century , immigrants from Russia , Eastern Europe and Italy , and African Americans from the southern U.S. settled in the city . Philadelphia was represented by the Washington Grays in the American Civil War . The African - American population of Philadelphia increased from 31,699 to 219,559 between 1880 and 1930 . Twentieth - century black newcomers were part of the Great Migration out of the rural south to northern and midwestern industrial cities .

Opening day ceremonies at the Centennial Exhibition at Memorial Hall , 1876 - first World 's Fair in the United States Opening day ceremonies at the Centennial Exhibition at Memorial Hall , 1876 - first World 's Fair in the United States By the 20th century , Philadelphia had become known as `` corrupt and contented '' , with an entrenched Republican political machine and a complacent population . The first major reform came in 1917 when outrage over the election - year murder of a police officer led to the shrinking of the City Council from two houses to just one . In July 1919 , Philadelphia was one of more than 36 industrial cities nationally to suffer a race riot of ethnic whites against blacks during Red Summer , in post-World War I unrest , as recent immigrants competed with blacks for jobs . In the 1920s , the public flouting of Prohibition laws , organized crime , mob violence , and police involvement in illegal activities led to the appointment of Brig. Gen. Smedley Butler of the U.S. Marine Corps as director of public safety , but political pressure prevented any long - term success in fighting crime and corruption . In 1940 , non-Hispanic whites constituted 86.8 % of the city 's population . The population peaked at more than two million residents in 1950 , then began to decline with the restructuring of industry , which led to the loss of many middle - class union jobs . In addition , suburbanization had enticed many of the more affluent residents to outlying railroad commuting towns and newer housing . The resulting reduction in Philadelphia 's tax base and the resources of local government caused the city to struggle through a long period of adjustment , with it approaching bankruptcy by the late 1980s . Revitalization and gentrification of neighborhoods began in the late 1970s and continues into the 21st century , with much of the development occurring in the Center City and University City neighborhoods . After many of the old manufacturers and businesses left Philadelphia or shut down , the city started attracting service businesses and began to market itself more aggressively as a tourist destination . Glass - and - granite skyscrapers were built in Center City beginning in the 1980s . Historic areas such as Old City and Society Hill were renovated during the reformist mayoral era of the 1950s through the 1980s , making those areas among the most desirable neighborhoods in Center City . These developments have begun a reversal of the city 's population decline between 1950 and 2000 during which it lost about one - quarter of its residents . The city eventually began experiencing a growth in its population in 2007 , which has continued with gradual yearly increases to the present . The geographic center of Philadelphia is located approximately at 40 ° 0 ′ 34 '' north latitude and 75 ° 8 ′ 0 '' west longitude . The 40th parallel north passes through neighborhoods in Northeast Philadelphia , North Philadelphia , and West Philadelphia including Fairmount Park . The city encompasses 142.71 square miles ( 369.62 km ) , of which 134.18 square miles ( 347.52 km ) is land and 8.53 square miles ( 22.09 km ) , or 6 % , is water . Natural bodies of water include the Delaware and Schuylkill rivers , the lakes in Franklin Delano Roosevelt Park , and Cobbs , Wissahickon , and Pennypack creeks . The largest artificial body of water is the East Park Reservoir in Fairmount Park . The lowest point is 10 feet ( 3 m ) above sea level , while the highest point is in Chestnut Hill , about 445 feet ( 136 m ) above sea level near the intersection of Germantown Avenue and Bethlehem Pike . Philadelphia is situated on the Fall Line that separates the Atlantic coastal plain from the Piedmont . The rapids on the Schuylkill River at East Falls were inundated by the completion of the dam at the Fairmount Water Works . The city is the seat of its own county . The adjacent counties are Montgomery to the northwest ; Bucks to the north and northeast ; Burlington County , New Jersey , to the east ; Camden County , New Jersey , to the southeast ; Gloucester County , New Jersey , to the south ; and Delaware County to the southwest . Philadelphia 's central city was created in the 17th century following the plan by William Penn 's surveyor Thomas Holme . Center City is structured with long straight streets running nearly due east - west and north - south , forming a grid pattern between the Delaware and Schuylkill rivers that is aligned with their courses . The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire . Penn planned the creation of five public parks in the city which were renamed in 1824 ( new names in parenthesis ) : Centre Square ( Penn Square ) , Northeast Square ( Franklin Square ) , Southeast Square ( Washington Square ) , Southwest Square ( Rittenhouse Square ) , and Northwest Square ( Logan Circle / Square ) . Center City had an estimated 183,240 residents as of 2015 , making it the second-most populated downtown area in the United States , after Midtown Manhattan in New York City . Philadelphia 's neighborhoods are divided into large sections -- North , Northeast , South , Southwest Philadelphia , West , and Northwest -- surrounding Center City , which corresponds closely with the city 's limits before consolidation in 1854 . Each of these large areas contains numerous neighborhoods , some of whose boundaries derive from the boroughs , townships , and other communities that constituted Philadelphia County before their inclusion within the city . The City Planning Commission , tasked with guiding growth and development of the city , has divided the city into 18 planning districts as part of the Philadelphia2035 physical development plan . Much of the city 's 1980 zoning code was overhauled from 2007 to 2012 as part of a joint effort between former mayors John F. Street and Michael Nutter . The zoning changes were intended to rectify incorrect zoning maps in order to facilitate future community development , as the city forecasts an additional 100,000 residents and 40,000 jobs will be added by 2035 . The Philadelphia Housing Authority is the largest landlord in Pennsylvania . Established in 1937 , it is the nation 's fourth - largest housing authority , housing about 84,000 people and employing 1,250 . In 2013 , its budget was $371 million . The Philadelphia Parking Authority works to ensure adequate parking for city residents , businesses and visitors . Philadelphia 's architectural history dates back to colonial times and includes a wide range of styles . The earliest structures were constructed with logs , but brick structures were common by 1700 . During the 18th century , the cityscape was dominated by Georgian architecture , including Independence Hall and Christ Church . In the first decades of the 19th century , Federal and Greek Revival architecture were the dominant styles produced by Philadelphia architects such as Benjamin Latrobe , William Strickland , John Haviland , John Notman , Thomas Walter , and Samuel Sloan . Frank Furness is considered Philadelphia 's greatest architect of the second half of the 19th century . His contemporaries included John McArthur Jr. , Addison Hutton , Wilson Eyre , the Wilson Brothers , and Horace Trumbauer . In 1871 , construction began on the Second Empire - style Philadelphia City Hall . The Philadelphia Historical Commission was created in 1955 to preserve the cultural and architectural history of the city . The commission maintains the Philadelphia Register of Historic Places , adding historic buildings , structures , sites , objects and districts as it sees fit . In 1932 , Philadelphia became home to the first modern International Style skyscraper in the United States , the PSFS Building , designed by George Howe and William Lescaze . The 548 ft ( 167 m ) City Hall remained the tallest building in the city until 1987 when One Liberty Place was completed . Numerous glass and granite skyscrapers were built in Center City beginning in the late 1980s . In 2007 , the Comcast Center surpassed One Liberty Place to become the city 's tallest building . The Comcast Technology Center is under construction in Center City with an expected completion in 2018 . The new tower will reach a height of 1,121 ft ( 342 m ) , and will be the tallest building in the United States outside of Manhattan and Chicago . For much of Philadelphia 's history , the typical home has been the row house . The row house was introduced to the United States via Philadelphia in the early 19th century and , for a time , row houses built elsewhere in the United States were known as `` Philadelphia rows '' . A variety of row houses are found throughout the city , from Federal - style continuous blocks in Old City and Society Hill to Victorian - style homes in North Philadelphia to twin row houses in West Philadelphia . While newer homes have been built recently , much of the housing dates to the 18th , 19th and early 20th centuries , which has created problems such as urban decay and vacant lots . Some neighborhoods , including Northern Liberties and Society Hill , have been rehabilitated through gentrification .

Summers are typically hot and muggy , fall and spring are generally mild , and winter is moderately cold . The plant life hardiness zones are 7a and 7b , representing an average annual extreme minimum temperature between 0 ° F ( − 18 ° C ) and 10 ° F ( − 12 ° C ) . Snowfall is highly variable with some winters having only light snow while others include major snowstorms . The normal seasonal snowfall averages 22.4 in ( 57 cm ) , with rare snowfalls in November or April , and rarely any sustained snow cover . Seasonal snowfall accumulation has ranged from trace amounts in 1972 -- 73 to 78.7 inches ( 200 cm ) in the winter of 2009 -- 10 . The city 's heaviest single - storm snowfall was 30.7 in ( 78 cm ) which occurred in January 1996 . Precipitation is generally spread throughout the year , with eight to eleven wet days per month , at an average annual rate of 41.5 inches ( 1,050 mm ) , but historically ranging from 29.31 in ( 744 mm ) in 1922 to 64.33 in ( 1,634 mm ) in 2011 . The most rain recorded in one day occurred on July 28 , 2013 when 8.02 in ( 204 mm ) fell at Philadelphia International Airport . Philadelphia has a moderately sunny climate with an average of 2,500 hours of sunshine annually , and a percentage of sunshine ranging from 47 % in December to 61 % in June , July , and August . The January daily average temperature is 33.0 ° F ( 0.6 ° C ) , though the temperature frequently rises to 50 ° F ( 10 ° C ) during thaws and dips to 10 ° F ( − 12 ° C ) for 2 or 3 nights in a normal winter . July averages 78.1 ° F ( 25.6 ° C ) , although heat waves accompanied by high humidity and heat indices are frequent , with highs reaching or exceeding 90 ° F ( 32 ° C ) on 27 days of the year . The average window for freezing temperatures is November 6 thru April 2 , allowing a growing season of 217 days . Early fall and late winter are generally dry with February having the lowest average precipitation at 2.64 inches ( 67 mm ) . The dewpoint in the summer averages between 59.1 ° F ( 15 ° C ) and 64.5 ° F ( 18 ° C ) .

hour particle pollution rating of D in the American Lung Association 's 2017 State of the Air report , which analyzed data from 2013 -- 15 . The city was ranked 22nd for ozone , 20th for short - term particle pollution , and 11th for year - round particle pollution . According to the same report , the city experienced a significant reduction in high ozone days since 2001 -- from nearly 50 days per year to fewer than 10 -- along with fewer days of high particle pollution since 2000 -- from about 19 days per year to about 3 -- and an approximate 30 % reduction in annual levels of particle pollution since 2000 . Five of the ten largest combined statistical areas ( CSAs ) were ranked higher for ozone : Los Angeles ( 1st ) , New York City ( 9th ) , Houston ( 12th ) , Dallas ( 13th ) , and San Jose ( 18th ) . Many smaller CSAs were also ranked higher for ozone including Sacramento ( 8th ) , Las Vegas ( 10th ) , Denver ( 11th ) , El Paso ( 16th ) , and Salt Lake City ( 20th ) ; however , only two of those same ten CSAs -- San Jose and Los Angeles -- were ranked higher than Philadelphia for both year - round and short - term particle pollution .

In 1815 , Philadelphia began sourcing its water via the Fairmount Water Works located on the Schuylkill River , the nation 's first major urban water supply system . In 1909 , the Water Works was decommissioned as the city transitioned to modern sand filtration methods . Today , the Philadelphia Water Department ( PWD ) provides drinking water , wastewater collection , and stormwater services for Philadelphia , as well as surrounding counties . PWD draws about 57 percent of its drinking water from the Delaware River and the balance from the Schuylkill River . The city has two filtration plants on the Schuylkill River and one on the Delaware River . The three plants can treat up to 546 million gallons of water per day , while the total storage capacity of the combined plant and distribution system exceeds one billion gallons . The wastewater system consists of three water pollution control plants , 21 pumping stations , and about 3,657 miles ( 5,885 km ) of sewers . Exelon subsidiary PECO Energy Company , founded as the Brush Electric Light Company of Philadelphia in 1881 and renamed Philadelphia Electric Company ( PECO ) in 1902 , provides electricity to about 1.6 million customers and more than 500,000 natural gas customers in the southeastern Pennsylvania area including the city of Philadelphia and most of its suburbs . PECO is the largest electric and natural gas utility in the state with 472 power substations and nearly 23,000 miles ( 37,000 km ) of electric transmission and distribution lines , along with 12,000 miles ( 19,000 km ) of natural gas transmission , distribution & service lines . Philadelphia Gas Works ( PGW ) , overseen by the Pennsylvania Public Utility Commission , is the nation 's largest municipally - owned natural gas utility . PGW serves over 500,000 homes and businesses in the Philadelphia area . Founded in 1836 , the company came under city ownership in 1987 and has been providing the majority of gas distributed within city limits . In 2014 , the City Council refused to conduct hearings on a $1.86 billion sale of PGW , part of a two - year effort that was proposed by the mayor . The refusal led to the prospective buyer terminating its offer . Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the Bell System went into effect . The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created , with the city and its northern suburbs retaining 215 . Overlay area code 267 was added to the 215 service area in 1997 , and 484 was added to the 610 area in 1999 . A plan in 2001 to introduce a third overlay code to both service areas ( area code 445 to 215 , area code 835 to 610 ) was delayed and later rescinded . In 2005 , a low - cost , citywide Wi - Fi service was approved for installation in the city . Wireless Philadelphia would have been the first municipal internet utility in a large U.S. city , but the plan was abandoned in 2008 as EarthLink pushed back the completion date several times . Mayor Nutter 's administration closed the project in 2009 after an attempt to revitalize it failed .
