In 2005, during the annual ‘intensive’ archaeological survey in the peri-urban zone of Sagalassus (Pisidia, southwest Anatolia), the remains of an extensive Classical-Hellenistic settlement were identified at Düzen Tepe, 1.8km southwest of Sagalassus. The results of three seasons of site investigation (2005–2007), comprising archaeological and geophysical surveys, architectural and topographical mapping, test soundings, and archaeometric and environmental research, are presented here, together with a discussion of the settlement's most probable socio-economic background. According to the latest results of all excavated or sampled survey ceramic artefacts and AMS C14 dating of faunal remains, the (proto-)urban settlement at Düzen Tepe was inhabited during the fifth to second century BC. It is the first of its kind to shed light on the material culture of the ancient inhabitants of the region, the ‘Pisidians’.
