The Ancient City of Pisidian Antioch (Antiocheia ad Pisidiam) is one of Turkey’s most important archaeological sites, located approximately 1 km northeast of Yalvaç in Isparta Province. Situated on the fertile plains at the southern foothills of the Sultan Mountains, the city played a vital role during the Hellenistic, Roman, and Byzantine periods.
Renowned as a major Roman colony, an early center of Christianity, and one of the cities visited by Saint Paul during his missionary journeys, Pisidian Antioch offers visitors a fascinating blend of history, archaeology, and religious heritage.
Foundation of the City
Pisidian Antioch was founded during the Hellenistic Period between 281 and 261 BC by Antiochus I Soter, the son of Seleucus I Nicator, founder of the Seleucid Empire.
Like several other cities established by the Seleucid dynasty, it was named Antiocheia in honor of its royal founder and became an important administrative and military center in the region of Pisidia.
Its strategic location overlooking the Anatolian plateau allowed it to control major trade and military routes connecting central Anatolia with the Mediterranean coast.
A Roman Military Colony
A major transformation occurred in 25 BC, when the Roman Emperor Augustus established Pisidian Antioch as one of the empire’s most important military colonies in Asia Minor.
Thousands of retired Roman legionaries were settled in the city, strengthening Roman control over the surrounding mountain tribes.
The colony officially became known as Colonia Caesarea Antiocheia, and Roman influence reshaped every aspect of urban life.
Wide paved streets, monumental public buildings, baths, temples, and administrative centers were constructed according to Roman urban planning principles.
Latin became the official language of government and administration, while Greek continued to be widely spoken among the local population.
Augustus and the Monumentum Ancyranum
One of Pisidian Antioch’s most significant historical treasures is the inscription of the Res Gestae Divi Augusti, the autobiographical account of Emperor Augustus’ achievements.
The best-known copy is preserved in Ankara at the Temple of Augustus, but another important version was discovered in Pisidian Antioch, highlighting the city’s prestige within the Roman Empire.
These inscriptions remain among the most valuable historical documents for understanding the reign of Augustus.
A Prosperous Roman City
During the height of Roman rule, Pisidian Antioch flourished as one of the largest cities in the region.
Archaeological evidence indicates that it featured:
- A monumental colonnaded street
- An impressive theater
- A Roman bath complex
- A large public square (Forum)
- Temples dedicated to Roman gods
- Aqueducts supplying fresh water
- City gates and defensive walls
- Residential districts with luxurious villas
Some historians estimate that the population may have exceeded 100,000 inhabitants, making it one of the major urban centers of inland Anatolia.
Saint Paul and Early Christianity
Pisidian Antioch occupies a special place in Christian history.
According to the Acts of the Apostles, Saint Paul and Barnabas visited the city during Paul’s First Missionary Journey around AD 46–48.
Paul preached in the city’s synagogue, where his message attracted many Gentile converts while also provoking opposition from some local authorities.
His sermons in Pisidian Antioch marked a turning point in the spread of Christianity beyond the Jewish communities of the eastern Mediterranean.
Today, visitors can explore the remains of St. Paul’s Church, believed to have been built over one of the earliest Christian worship sites in the city.

Byzantine Period
Following the spread of Christianity, Pisidian Antioch became an important episcopal center within the Byzantine Empire.
Many pagan temples were converted into churches, while new basilicas, monasteries, and religious buildings were constructed throughout the city.
Although the city gradually declined after Arab raids and changing trade routes, it remained inhabited for several centuries.
