 With the fall of Acre and collapse of the Kingdom of Jerusalem by the Mamluks under Sultan al-Ashraf Khalil, the Knights Templar lost their main roles of defence of the Holy land and security of pilgrims to the Holy Sites.The castle could now only be resupplied by sea, so the castle was evacuated between 3 and 14 August 1291.The castle was not demolished by the Mamluks as was their normal practice after capturing a crusader fortification and remained in good condition until it suffered severe damage during the Galilee earthquake of 1837, and was also further damaged by Ibrahim Pasha in 1840, who used it as a source of stone for Acre.
