Gorgobina — Wikipedia

Gorgobina, also Gortona, was an oppidum of the Boii in central Gaul. It is known only from Caesar's account of the Gallic War, as the stronghold of the Boii whom the Aedui had received in 58 BC and settled on the edge of their territory. In 52 BC it was besieged by Vercingetorix, an event that drew Caesar into the campaign in Biturigan territory. Its site has not been securely identified, but is generally placed at Sancerre or the neighbouring Saint-Satur (Cher). However, no remains of the period have been found at those places.
