added by archaeologs Iron Age hillfort in Cote-d'Or, France, on a route from the River Seine to the Mediterranean. Occupation is dated to the 6th century BC (Hallstatt D), the residence of a Celtic chieftain. The hillfort of Vix seems to have been the center of political authority and extensive trade relations. The rich Celtic and Greek artifacts found there, including Massiliote wine amphorae and Attic black figure ware, as well as those from the nearby tumulus burials near the villages of Vix and Sainte-Colombe-sur-Seine, indicate trade between the Celts and the Greeks.
