Demirci Höyük

Demirci Hüyük is an excavated settlement in ancient northwestern Anatolia dating from the Early and Middle Bronze Age. It is located near the village of Zemzemiye, Söğüt, about 25 km west of Eskisehir on the border of the Bilecik and Eskisehir Provinces.

The western side of the hill has been eroded by the Zemzemiye Creek passing by. The plain on which Demirci lies was filled up with sediment since the Neolithic period, so the village of Demirci's first inhabitants was excavated about 7–8 m below the plain level. The cultural deposit is about 12 m thick.

Sariket, an ancient burial ground, is on the terrace 250 m west of Demircihöyük settlement. It was used as a necropolis both during EBA and MBA. During the Hellenistic Period there were also a few inhabitants living on the top of the Demirci hill.
