Beirut (Arabic: بيروت Bayrūt, Greek: Βηρυττός, Latin: Berytus, French: Beyrouth, Hebrew: ביירות Beyrut) is the capital and largest city of Lebanon. As there has been no recent population census, the exact population is unknown; estimates in 2007 ranged from slightly less than 1 million to slightly more than 2 million. Located on a peninsula at the midpoint of Lebanon's Mediterranean coast, it serves as the country's largest and main seaport. The Beirut metropolitan area consists of the city and its suburbs. The first mention of this metropolis is found in the ancient Egyptian Tell el Amarna letters, dating from the 15th century BC. The city has been inhabited continuously since then.
