Tourism in Libya is an industry heavily hit by the Libyan Civil War. Before the war tourism was developing, with 149,000 tourists visiting Libya in 2004, rising to 180,000 in 2007, although this still only contributed less than 1% of the country's GDP. There were 1,000,000 day visitors in the same year. The country is best known for its ancient Greek and Roman ruins and Sahara desert landscapes.
