Bibracte

A fortified Gallic oppidum on Mont Beuvray in Burgundy, France, capital of the Aedui tribe, founded in the late 3rd century BC and spanning 200 hectares. In 58 BC, Caesar defeated the Helvetii near Bibracte, and in 52 BC Vercingetorix was proclaimed supreme commander of the Gallic coalition here. The site was gradually abandoned after Augustus founded nearby Augustodunum (Autun) around 15 BC. Rediscovered through 19th-century excavations by Jacques Gabriel Bulliot, Bibracte now hosts an archaeological museum and ongoing research center.
