Origin of the name Vérossaz

The name appears in 1046 as « Verolsa ». It reportedly comes from the Franco-Provençal verossa, meaning the mountain alder, a word probably of Gaulish origin.[1]

Founding of Vérossaz

A Bronze Age axe has been found on the plateau above Saint-Maurice, but the plateau does not seem to have been permanently settled before the 11th century. After the death of Rudolph III, the last king of Burgundy, the territory passed to the House of Savoy and belonged to the castellany of Saint-Maurice: the mayoralty of Les Haussex and Les Bassex belonged to the abbey of Saint-Maurice, La Doey to Savoy. Vérossaz was later part of the governorship, then the district of Saint-Maurice. Long part of the large municipality of Saint-Maurice, it separated from it to become independent. It joins the hamlets of Les Haussex, its main core, Les Bassex, La Doey, Chavanne and Vésenaud. Who founded Vérossaz is not known.[1]
