An Iron Age Gallic town and oppidum in central France. It was the capital of the Aedui tribe at the time of Caesar and the site where he defeated the Helvetii tribe, the climax of his first campaign in Gaul (58 BC). Augustus moved the inhabitants to his new town Augustodunum (Autun), about 30 km away, in 12 BC. Excavations in the 19th century revealed remains of both the Iron age settlement and the Roman period, including a large temple, houses, and metalworking workshops. Imported objects such as coins, amphorae, black and red glaze pottery dating to before the Roman conquest have been found, indicating that Bibracte was a major trading and production center in the late Iron Age.
