The croutons Pont-Saint-Martin with the classic black bread made with rye flour, mushrooms and delicious fontina cheese, are characteristic of the homonymous municipality that lies on the border between the Val d'Aosta and Piedmont, it is known for its historical carnival, the oldest in the region.
Legend has it that the Roman bridge, the first century BC, characteristic of the town, was built as a result of a deal, that Saint Martin, on the Via Francigena pilgrimage, made with the devil. In fact, St. Martin promised to the devil, in exchange for the construction of the bridge, the soul of the first living being that he had gone through.

After construction, San Martino released on the bridge a poor little dog who, unaware, was offered in sacrifice. Tricking the devil that he did not get the soul of any human being, the inhabitants were thus left alone by the devil. The name of Pont-Saint-Martin has identified the area for a very long time until it officially became the real name of the municipality.
