The construction time of Ankara Castle, one of the oldest buildings in Ankara, is not clearly known. The castle, which came under the control of the Turks with the entry of the Turks into Anatolia, has been used as a Turkish military facility for many years since then.
The height of the castle from the ground is 110 meters. The castle consists of an inner castle covering the high side of the hill and an outer castle covering the surrounding area. The outer castle has nearly 20 towers. The outer castle is around the old city of Ankara.
