Collapse of the northern Crusader watch tower at the end of the city wall, the tower was almost whole at the early 20thcentury, in recent years it totally collapsed. On the shallow sea bottom opposite the remains of the tower (to the north) there are polygonal columns (2 m long) with perforation at their upper end. They are arranged in a row. They served as a burrier to prevent invasion of hostile troops to the castle via the shallow sea
