Sagalassos is in southwestern Turkey about 100 km north of Antalya and 30 km to Burdur and Isparta, two largest towns in the proximity. The ruins are the best preserved in Anatolia partly due to distant location at high altitudes in the mountains of the western Taurus range. In Roman era it was one of the principal Pisidian towns. The houses were scattered on terraces at elevations 1400 m up.

Sagalossos passed into the Roman hands in 39 BC when it was a city of the kingdom of Pergamons; Galatians, an ally of Romans, administered Sagalossos for Romans until Galatians king Amyntas was killed in an ambush for revenge. After his death Galatia became a Roman province. Under Roman rule the city received favours, especially in the reign of Harian who made it a cult cult center.

The excavations carried out from 1990 on at the site exposed a large number of archeological remains.
