Formerly called Merdogne plateau, the vast Gergovie plateau, located 15 kilometres south of Clermont-Ferrand, is famous for being the site of the famous Battle of Gergovia that took place between Vercingetorix and Julius Caesar's armies in 52 BC. A commemorative monument erected by Napoleon III in honour of Vercingetorix stands on one edge of the plateau. From this site, there's a fantastic view of Clermont-Ferrand, its suburbs and the Limagne plain below.
Worth visiting: the Maison de Gergovie, an information centre devoted to the geology, archaeology and history of the plateau.
Two not-to-be-missed events take place on the plateau: Les Arverniales, a weekend-long archaeology festival every July that features living history displays of the Gallic period; and Cervolix, an impressive annual kite festival every second weekend of October.
