The Castle of Alanya, with 83 towers, 140 bastions and walls nearly 6.5 kilometres long, rises up to 250 metres from sea level. The castle was constructed by the Sultan of Selcuks, Alaaddin Keykubat, who conquered the city in 1221. An open-air museum is located at the peak of the peninsula where Alaaddin Keykubat, the Sultan, had his palace.
Today the castle is still inhabited by people. In front of wooden and brick houses, silk and cotton are woven, white gourds are painted in different figures and authentic meals are served in small gardens. There are also restaurants and cafes on the way to the castle overlooking the harbor and offering breathtaking views of the town, Taurus mountains and the Mediterranean sea. The castle is open to traffic and a taxi is very recommended when visiting the castle.
