Sagalassos , originally uploaded by voyageAnatolia.blogspot.com . Sagalassos is an archaeological site in southwestern Turkey, about 100 km north of Antalya, and 30 km from Burdur and Isparta. The ancient ruins of Sagalassos are 7 km from Ağlasun in the province of Burdur, on Mount Akdağ, in the Western Toros mountain 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. Sagalassos was one of the wealthiest cities in Pisidia when Alexander the Great conquered it in 333 BCE on his way to Persia.
