File:Antioch in Pisidia Theatre 2963.jpg

English: The original architecture of the theater can be dated back to the founding of the colony (25 BC) or may even go back to the Hellenistic age. It was built north of the Decumanus Maximus (the main east–west-oriented street), adjacent to it. The theater was enlarged in 311-313 AD. Its dimensions are similar to those of the theater in Aspendos, which had a capacity of 12.000 people. This theater was rather bigger and larger than the other important Pisidian city theaters at Sagalassos, Termessos and Selge.

Numerous stone blocks of the building have been carried away for later period constructions, both in Antioch and in Yalvaç; in 1833 already, when he identified the theater, Arundell observed that many blocks had been removed.

A notice at the gate gives: "Antiocheia is on a hill approximately 1236 m high and lies 1 km north of Yalvaç County of Isparta Province. The city is surrounded my the Sultan Mountains to the east, Karakuş Mountain to the north, Kızıldağ Mountain to the southeast, Kirisli Mountain and northern shore of Eğirdir Lake to the southwest. The acropolis of the citadel, which is surrounded by city walls, has an area of 47 hectares. The antique city was founded my Antiochus I from the Seleucid dynasty, between 281 BC – 261 BC and was called “Antiocheia”. Emperor Augustus, who established the first an greatest military colony in Pisidia, honoured the city with the title of Caesareia in 25 BC. The city became the capital of the region and a rich metropolis during the Roman Period. In the Early Empire Period the city was reconstructed on a new systematic plan, and many religious and secular buildings were built. The currently known buildings with the grid plan are the Augustan Temple, Theatre, Roman Bath, St. Paul’s Church, Central Church, Northern Church, Tiberius Square and Nymphaeum, besides these, Decumanus Maximus, Cardo Maximus, Western Gate and Propylon are also excavated at the archaeological site. St. Paul, one of the twelve apostles of Jesus Christ who played an essential role in the spreading of Christianity with his political identity, made three journeys from Jerusalem to Antiocheia, the capital of Pisidia. He lived there as a tent maker for two years. He taught Christianity by addressing the people of different faiths, and he preached Christianity from Antiocheia. All these factors further increased the importance of Antiocheia."
