Mamure Castle is one of the most intact Turkish castles on the Mediterranean coast. It is located within the boundaries of the village of Bozdoğan, 6 km east of Anamur, on the Antalya-Mersin highway. The castle, like many other Anatolian castles, was built on ancient foundations. However, the exact date and the identity of the builders of the ancient foundations are unknown. It was expanded and used in the Roman period to protect trade routes and to guard merchant ships. During the Byzantine and Crusader periods, the area of the castle was further expanded. During the reign of the Seljuk Emperor Alaeddin Keykubat, the castle was conquered in 1228. With the weakening of the Seljuk state, it came under Christian control. It was later taken over by Karamanoglu Mahmut Bey. The castle was rebuilt by Karamanoglu Sultan Ibrahim in 1450 and named Mamure Castle. It comprises three distinct sections: the inner courtyard in the east, separated by high walls; the outer castle in the west; and the inner castle, built on the rocks in the south. There are 39 towers, water cisterns, a mosque and a bathhouse on the outside, while the walls are surrounded by a 10-metre-wide defensive moat.
