Its distance to Bozyazı is 8 km (5.0 mi) and to Mersin is 207 km (129 mi).
Within the castle, which is mostly in ruins, there is a monastery with two wide halls, a part of a basilica and a courtyard. There are remains of mosaics with geometric design in the monastery. The windows are round arch type. There are two cisterns and two towers of about 6–7 m (20–23 ft) height in the west of the castle.
