Antiocheia Archaeological Site

Antiocheia was a Pisidian city on the fertile southern slopes of the Sultan Mountains, about a kilometre north of today's Yalvaç in Isparta province. After the death of Alexander the Great it was founded by his general Seleucus I and Seleucus's son Antiochus.

The walled acropolis covers around 46 hectares. Visitors enter through the west gate, a triumphal arch with three passages that shares its architectural and sculptural approach with the Propylon leading to the Temple of Augustus. The city follows a regular grid, the so-called Hippodamian plan, named for the architect Hippodamos of Miletus. Shops lined the main street, the Decumanus Maximus, which starts at the West Gate.

Among the remains are a theatre built in the Hellenistic period, two squares named for Augustus and Tiberius, an aqueduct, a bath, a nymphaeum, the Temple of Augustus and the church of St. Paul, which places the site among the sites associated with early Christianity in Anatolia.

Its scale and clear layout make it easy to read as a city.
