On one of the hills that face Golturkbuku is Madnasa (Kokpinar Tepesi) and the other hill Sibda/Side (Karadag). In both cities there are the remains of walls and towers from the acropolis and some ceramic and pottery pieces. In order to get to Sibda you have to turn off the road to Yukari Golkoy and go to the village of Belen by car. By walking from Belen for 40 minutes you get to the ruins of a church and a castle. Another 40 minutes walk gets you to Karadag where the ruins of Sibda are to be found. While the ruins are not very spectacular the view that gives you a panorama of the Bodrum peninsula are.
