Chokepoint fortress on the roads from Tripoli to Tartus and Homs. Raymond of Toulouse besieged it unsuccessfully for three months in 1099 during the First Crusade; William II Jordan finally took it in 1108 and incorporated it into the County of Tripoli. The castle resisted Nur ad-Din in 1167 and 1171 before falling to Baibars in 1265–66.
