Alesia

Alesia is the hilltop Gaulish oppidum on Mont Auxois, roughly 50 kilometers northwest of Dijon, where in 52 BC Julius Caesar decisively defeated the Gallic chieftain Vercingetorix in one of antiquity's most celebrated sieges. Caesar encircled the fortress with a double ring of earthworks — an inner circumvallation to trap Vercingetorix and an outer contravallation to repel a Gaulish relief army — a feat of military engineering described in his own Commentarii de Bello Gallico. The exact location of the battle was disputed for centuries until Napoleon III funded large-scale excavations at Alise-Sainte-Reine in the 1860s, settling the mainstream scholarly consensus. Today the MuséoParc Alésia combines active archaeological dig sites with a purpose-built interpretation center covering both Roman siege tactics and Mandubii Gaulish culture, while the plateau itself offers sweeping views across the Burgundian countryside.
