In the early 1990's, a team led by E. Varinlioğlu and P. Debord, carrying a survey in northern Karia, reached a remote ancient settlement located at more than 1100 m in altitude, on the western slope of the Madran mountains, between the valleys of Marsyas (Çineçay) and Harpasos (Akçay). The path leading to the site passes through the village of Topçam and continues 2.6 km further north in a rocky and steep landscape. Due to the difficulties in reaching the spot, the team could only spend a few hours onsite and concentrated on the architectural remains. A sketch map of the settlement was done by using a GPS hand-device, completed by a precise documentation of both the well-preserved tower and the monumental tomb 1.
