At the southern end of the mountain range is the plain (the Homs Gap) which separates it from Mount Lebanon, in the country of Lebanon. On the south end is Krak de Chevaliers, a castle of the Middle Ages. In Classical Antiquity, the fresh water that came from these mountains supplied the cities of Antioch, Seleucia Pieria, Apamea, and Laodicea. Laodicea (now Latakia) was famous for its wine (from vines grown in this region), and the Roman geographer Strabo wrote that most of the wine in Alexandria in Roman Egypt came from Laodicea. Latakia was famous in the more recent past for its tobacco production.
