Explore South Central Anatolia Lakeland Cappadocia Share The ancient city of Antioch ad Pisidiam is where the apostle St Paul first attempted to convert pagans to Christianity. Originally a Hellenistic foundation of the late third century BC, the city peaked as the capital of the Roman province of Pisidia, and remained important well into Byzantine times. The most unusual surviving remains are of the sizeable temple, at the highest point of the city, built in a semicircular colonnaded precinct in honour of the Emperor Augustus. Below this is the toppled three-arched propylon (gateway) dedicated to Augustus, where the Tiberius and Augustus squares meet. Even more substantial are the remains of the baths fed by an aqueduct and surviving sections of a flagged Roman street. At the lower end of the site, a few courses of monumental stone blocks belonging to the fourth-century Church of St Paul (on the site of the synagogue) still stand, but little else can be seen except for the ground plan and some small areas of mosaic floor.
