Byblos
Byblos is one of the oldest inhabited cities in the world, tracing back to around 8800 years B.C. The city contains historical ruins including a castle and the church which were originally built by the Crusaders in the 12th and 13th centuries AD . The castle holds a historical story where it has been built, surrendered and regained by Crusaders.

The roof is usually used for sightseeing providing an exquisite view of the port and the old remains of the city. The city Sidon by itself has become a touristic destination because of its value in the history of the country as a whole and for the beauty of its architecture. Beirut 
Archaeological artifacts show Beirut was settled back to the Iron Age. Beirut was a city of glory during the Roman era. It then became occupied by different civilizations some of which were the Crusaders in 1109, the Mamluks in 1291 and then Ottomans who stayed in Lebanon for 400 years until 1916. The country then went through a period of French mandate until 1943. During this period European architecture was introduced. Up until the first half of the 19th century it was not as significant as other cities along the Mediterranean Sea coast (Tripoli and Damascus), and few pre-19th century landmarks remain, apart from some religious buildings. In 1831 Ibrahim Pasha established himself in the city in the wake of his struggle against Ottoman rulers. The toll road to Damascus was constructed in 1863, Orozdi Bek Department store in 1900, and the Arts and Crafts School in 1914. The city now features modern buildings alongside arabesque Ottoman buildings, as well as Roman and Byzantine structures. Beirut is famous for a group of five columns that were discovered underground in the heart of the city in 1963, found to be a small part of a grand colonnade of Roman Berytus. Religious architecture

Roman temples include the Temples of Baalbek, Temple of Eshmun and ancient temples in Niha. There are thousands of churches in Lebanon that include but are not limited to: Saint George Maronite Cathedral of Beirut, Saint Louis Cathedral, Beirut, Saint George Maronite Cathedral, Beirut, Saint George Greek Orthodox Cathedral, Bzoummar, and St. Elie and St. Gregory the Illuminator Armenian Catholic Cathedral.

The Beit ed-Dine palace complex was built by Amir Bechir El-Chehab II in the early 19th century. The palace entrance leads through the gates into an open space. This area was originally used for cavalry practices and for celebrations, which were attended by the public, visitors and important people of that time. The palace complex is now a museum with pictures, transcripts and documents including a collection of ancient pottery. It also contains a collection of Romanian gold jewelry, Islamic glazed wares, ethnographic objects, and ancient and modern weapons.

New primary and secondary schools were also established. 20th century and Classical architecture to Modernism

The first residential houses in Lebanon were the Phoenician houses. They were bricks and the roofs where always formed from massive rocky segments. The perception deriving the method of building a house met some changes after the third millennium BC when the walls of the houses increased in height, some houses were built with stones, others remained rectangular and all increased in dimensions. The exterior and the interior walls where covered sometimes with mud. Lebanese houses incorporated the rules of the Ottoman Empire and the exit of the French mandate. Architects
