The Crusaders who conquered so much Byzantine territory also seized a variety of fortifications. These they mostly reused and strengthened. Cyprus, despite its seemingly exposed situation in the eastern Mediterranean, had not been strongly fortified by the Byzantines and the important town of Famagusta had only minor defences. The Crusaders now added more, strengthening Famagusta’s two or three gates and constructing a tower to control the harbour entrance. Under Lusignan rule there were four types of fortification in Cyprus: isolated mountain-top castles in the north of the island, such as Buffavento, St Hilarion, and Kantara; coastal towns with citadels, such as Paphos, Limassol, and Magusa; inland towns with minimal defences, such as Nicosia; and small rural castles.
