 Under Frankish rule, the villages of the district of Kyrenia became feudal estates and the town became once again the administrative and commercial centre for its region.The Lusignans enlarged the castle, built a wall and towers around the town, and extended the fortifications to the harbour.They also fortified the Byzantine castles of Saint Hilarion, Bouffavento and Kantara, which, together with Kyrenia Castle, protected the town from land and sea attacks.
