What is "sagalassos"

Sagalassos is an archaeological site in southwestern Turkey, about 100 km north of Antalya (ancient Attaleia), and 30 km from Burdur and Isparta. The ancient ruins of Sagalassos are 7 km from Ağlasun (as well as being its namesake) in the province of Burdur, on Mount Akdağ, in the Western Taurus mountains range, at an altitude of 1450–1700 metres. In Roman Imperial times, the town was known as the "first city of Pisidia", a region in the western Taurus mountains, currently known as the Turkish Lakes Region. Already during the Hellenistic period, it had been one of the major Pisidian towns.
