Gibelacar, also known by its original Arabic name Hisn Ibn Akkar or its modern Arabic name Qal'at Akkar, is a fortress in the village of Akkar al-Atiqa in the Akkar Governorate in northern Lebanon. The fortress dates back to the Fatimid era in the early 11th century. It was captured and utilized by the Crusaders in the early 12th century until it was captured and strengthened by the Mamluks in the late 13th century. It became the headquarters of the Sayfa clan, whose members, chief among them Yusuf Pasha, served as the governors and tax farmers of the Tripoli Eyalet and its sanjaks from 1579 through the mid-17th century.
