Panama City  Panama City (; ), also simply known as Panama, is the capital and largest city of Panama. It has an urban population of 880,691, with over 1.5 million in its metropolitan area. The city is located at the Pacific entrance of the Panama Canal, in the province of Panama. The city is the political and administrative center of the country, as well as a hub for banking and commerce. The city of Panama was founded on 15 August, 1519, by Spanish conquistador Pedro Arias Dávila. The city was the starting point for expeditions that conquered the Inca Empire in Peru. It was a stopover point on one of the most important trade routes in the American continent, leading to the fairs of Nombre de Dios and Portobelo, through which passed most of the gold and silver that Spain took from the Americas. On 28 January, 1671, the original city was destroyed by a fire when the privateer Henry Morgan sacked and set fire to it. The city was formally reestablished two years later on 21 January, 1673, on a peninsula located from the original settlement. The site of the previously devastated city is still in ruins, and is now a popular tourist attraction, and is regularly visited by school trips. The city was founded on 15 August, 1519, by Pedro Arias de Ávila, also known as Pedrarias Dávila. Within a few years of its founding, the city became a launching point for the exploration and conquest of Peru and a transit point for gold and silver headed back to Spain through the Isthmus. In 1671 Henry Morgan with a band of 1400 men attacked and looted the city, which was subsequently destroyed by fire. The ruins of the old city still remain and are a popular tourist attraction known as Panamá Viejo (Old Panama). The city was rebuilt in 1673 in a new location approximately southwest of the original city. This location is now known as the Casco Viejo (Old Quarter) of the city. Panama City is the fourth earliest-founded of the modern-day capital cities in the Americas. One year before the start of the California Gold Rush, the Panama Railroad Company was formed, but the railroad did not begin full operation until 1855. Between 1848 and 1869, the year the first transcontinental railroad was completed in the United States, about 375,000 persons crossed the isthmus from the Atlantic to the Pacific, and 225,000 in the opposite direction.
