Bourg-Saint-Maurice, popularly known as Bourg, is a commune in the Savoie department in the Rhône-Alpes region in south-eastern France. It is the last large town along the Tarentaise valley in the heart of the French Alps. 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). D'Anville (Notice, etc.) places it, according to the Table, between Axima (modern Aime) and Alpis Graia.
The distance from Bergintrum to Axima is 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.
This is the place D'Anville calls l'Hôpital, on the authority of a manuscript map of the country. D'Anville first proposed the identification of Bergintrum with Bourg-Saint-Maurice; although he acknowledged that xii, the distance in the Table between Bergintrum and Alpis Graia, does not fit the distance between Bourg-Saint-Maurice and l'Hôpital, which is less. Modern scholarship confirms the identification.
