The site of the Crusader Castle was originally occupied by an earlier fortification dating from the Fatimid period (969-1169 A.D.). In the beginning of the 12th century A.D., the Crusaders built a strong fortress, reusing Roman stonework from the site and cutting new stones to match the old ones.
The castle consisted of a courtyard, an enclosure with four towers at each corner of the building, and a fifth tower in the middle of the north wall to defend the entrance. The whole castle was originally surrounded by a moat. In Mamluke and Ottoman times, the castle was reused and some parts of it were restored.
Climbing to the top of the castle offers an excellent vantage point for taking in a panoramic view of the ruins and the Mediterranean Sea. * 28 April 1103 Raymond de St. Gilles captures the town with the aid of Genoese ships.
