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."
