The ancient site of Sagalassos is located on the hillside of Mount Akdag of Taurus mountain range near Aglasun village in southwestern Turkey, about 33 km to Burdur province and 110 km from Antalya. The site covers and area of 2,5 km by 1,5 km at an altitude of approximately 1500 meters, being one of the biggest archaeological sites in Turkey.
Sagalassos was the most important city for the Romans in the Psidian region of Asia Minor. But it's known that the city was famous also during the Hellenistic period when Alexander the Great captured it in 334 BC. After his death, the region passed first under the control of the Seleucids of Syria and then under the Attalids of the Pergamon Kingdom around 189 BC. Between 1st century BC and 6th century AD the city lived its heydays, we understand this from high quality potteries made during that period and also from monumental buildings. After a major earthquake in the 7th century, its inhabitants left the city and settled in the valley and lived there until 12th century, then Sagalassos disappeared. The ancient site was discovered in 1706 by a French traveler, and first excavations started in 1990 by Belgian archaeologists. Today, the excavations are sponsored by Aygaz, a private energy company belonging to Koc family in Turkey.
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.
The site can not be visited during winter months due to heavy snow.
