 The castle's position dominated the north-south coastal route, and surrounding countryside allowing it to draw revenue from tolls and rents, going some way to pay for the running costs of the castle; as well as providing protection for pilgrims.The castle probably got its name from pilgrims who volunteered their labour during its construction.There is a large Crusader cemetery (80 x 100 metres) north of the castle, on the beach, containing hundreds of graves, some with carved grave markers.
