Bergintrum was a place on the Gallic side of the pass of the Alpes Graiae, lying on the road marked in the Antonine Itinerary between Mediolanum (modern Milan) and Vienna (modern Vienne, Isère). Jean-Baptiste Bourguignon d'Anville (Notice, etc.) placed it between Axima (modern Aime ) and Alpis Graia. The distance from Bergintrum to Axima, marked viiii M. P. The Alpis Graia, is usually identified with a settlement at the watershed on the Pass of the Little Saint Bernard, which divides the waters that flow to the Isère on the French side from those that flow to the Dora Baltea on the Italian side.
