About
About Tavium (Büyükkale / Büyüknefes)
Capital of the Galatian Trocmi, Tavium sits on a fortified limestone ridge (Büyükkale) dominating the Halys bend at modern Büyüknefes. First Greek source Strabo (Geogr. 2) calls it the tribe’s emporion with a colossal bronze Zeus statue (Bryaxis) and its own coinage. 6 km long with Phrygian rock tombs under the citadel enclose a Roman grid still visible on magnetometry; inscriptions record treaties with Rome (189 BCE) and the Galatian tetrarch Deiotarus.
Rescue work has revealed a Roman colonnaded avenue, Hellenistic lower-town terracing and a 2nd-century CE aqueduct. The mound preserves Bronze Age beneath Galatian fill, explaining the toponym’s persistence from Hattic Tawia.
Why it mattersOnly archaeologically confirmed Galatian tribal capital; key to Celtic migration and Roman Galatia urbanism.
