Tavium, or Tavia (Ancient Greek: Τάουιον Taouion; Latin: Taouion or Tavium), was the chief city of the Galatian tribe of Trocmi, one of the three Celtic tribes which migrated from the Danube Valley to Galatia in present-day central Turkey in the 3rd century BCE. Owing to its position on the high roads of commerce was an important trading post. The site was successively occupied by Hittites, Cimmerians, Persians, Celts, Greeks, Romans, Seljuk Turks and Ottoman Turks. At the time of the Roman Empire, Tavium was an important crossroads and a stopping place on the caravan routes.
