The Crusaders captured the city from the Arabs in May 1101. By then the city had already been severely reduced in size; the crusader city occupied essentially the walled area, with a population of just about 12 thousand. The city was later fortified with a 10m wall behind the moat (most of which have since been destroyed).
The defences, however, did not prevent the Mamluks from laying siege to the city in February 1265. In the midst of negotiations the Crusader inhabitants made their escape by night to Acco. In response the Mamluks razed the city to the ground. The city lay abandoned until the Ottomans resettled it with Muslim refugees from Bosnia beginning 1878. Their settlement was, in turn, razed to the ground in the 1948 war.
