The archaeological site of Sagalassos is located in southwest Turkey, near the present town of Ağlasun (Burdur province); roughly 110 km to the north of the well-known port and holiday resort of Antalya.

Large-scale excavations started in 1990.Most of the buildings in Sagalassos are from Hellenistic and Roman periods and well preserved, one of them is the great theater with a capacity of 9,000 people. This is a theater built on the highest altitude in the world. The city has many tombs carved into the rocks, a library, Heroon, Bouleterion (city council), temples, baths, agoras (market place), and monumental fountains which are also intact or restored. Many marble sculptures found during the excavations, belonging to ancient gods such as Ares, Herakles, Hermes, Zeus, Athena and Poseidon, and colossal statues of the emperor Hadrian, emperor Marcus Aurelius, and Faustina as the wife of the emperor Antoninus Pius, are one of the best examples of this art in Anatolia.
