Beirut is the capital and largest city of Lebanon. Located on a peninsula at the midpoint of Lebanon's Mediterranean coast, Beirut is the country's largest and main seaport. It is one of the oldest cities in the world, inhabited more than 5,000 years ago. The first historical mention of Beirut is found in the ancient Egyptian Tell el Amarna letters dating from the 15th century BC. The Beirut River runs south to north on the eastern edge of the city. Beirut is Lebanon's seat of government and plays a central role in the Lebanese economy, with many banks and corporations based in its Central District, Badaro, Rue Verdun, Hamra and Ashrafieh. Following the destructive Lebanese Civil War, Beirut's cultural landscape underwent major reconstruction. In May 2015, Beirut was officially recognized as one of the New7Wonders Cities together with Vigan, Doha, Durban, Havana, Kuala Lumpur, and La Paz.
