The territory of the Sarre was probably inhabited in the Bronze Age and traces of human settlements, in fact, have been found in various points in Ville sur Sarre, near the village of Saint Maurice and the area at the foot of the mountain, once the location of the road which connected the area with the Gallia. It is assumed that these sites were inhabited until the period of conquest by the Romans, when they were abandoned. In the medieval period Sarre was subjected to the lords and nobles of the Families of Bard and Quart. In 1783 the towns of Chesallet and Sarre were combined in a single center as until then they had been independent one from each other. The territory was for a long period under the domination of the Savoy. During the Fascist period, the town was united to Aosta, losing its autonomy, which it regained in 1946.
