GERGOVIA (mod. Gergovie), in ancient geography, the chief settlement of the Arverni, situated in the Auvergne, 8 m. from the Puy de Dome, France. Julius Caesar attacked it in 52 B.C., but was beaten off ; some walls and earthworks, probably of this period, survive. Later, when Gaul had been subdued, the place was dismantled and its Gaulish inhabitants resettled 4 m. away in the plain at the new Roman city of Augustonemetum (mod. Clermont-Ferrand).
