The impressive Beqaa Valley separates the Lebanon from the Anti-Lebanon mountain ranges. This highly fertile valley lies at an altitude of over 850m, between mountain peaks that reach 3000m, and provides Lebanon with much of its agricultural farms. Its dramatic topography was created by the same geological fault line that gave us the Dead Sea and the Red Sea further south. Two important rivers run through it: the Orontes and the Leontes, known in Arabic as
al-Assi and
al-Litani and run northwards and southwards, respectively. The Beqaa, named
Coelesyria (i.e., "hollow" Syria) in the Graeco-Roman world, is home to some of Lebanon's most impressive ancient ruins, namely
Baalbek and
Aanjar, as well as
Lebanon's wine industry.
