The Antiochia ad Cragum Archaeological Research Project is an international collaborative initiative investigating the archaeology, history, and environment of the Roman to Byzantine port city of Antiochia ad Cragum on the coastline of Turkey (Türkiye). Cilicia’s location made it a locus for sociocultural and economic exchange between the Near East, central Anatolia, and coastal Asia Minor, facilitating integration across the Roman Empire. Antiochia, the only newly founded city of Antiochus to be systematically excavated, grew to be one of Rough Cilicia’s principal ports and remained a dynamic and prosperous city for centuries, continually transformed as its inhabitants adapted to evolving political, social, economic, and religious practices.
