Aosta (French: Aoste) is the principal city of the bilingual Aosta Valley in the Italian Alps, 110km north-northwest of Turin. It is situated near the Italian entrance of the Mont Blanc Tunnel, at the confluence of the Buthier and the Dora Baltea, and at the junction of the Great and Little St. Bernard routes. Aosta is not the capital of the province, as these functions are shared by the region and the communes.
