There have been other theories about Alesia's location that claimed it was in Franche-Comté or around Salins-les-Bains in Jura. In the 1960s, a French archaeologist, Andre Berthier, proposed that the location of Alesia is at Chaux-des-Crotenay in Franche-Comté, at the gate of the Jura mountains - a place that better suits the descriptions in Caesar's Gallic Wars - and indeed, Roman fortifications have been found at that site.
