Neung sur Beuvron is thought to be the Roman town of Noviodunum Biturigum, in which Vercingetorix and Julius Caesar fought in 52 BC.
His sieges of Vellaunodunum, Genabum and Noviodunum en route caused Vercingetorix to lift his siege and march to meet Caesar in open battle at Noviodunum, which Caesar won.
