 After the fall of the Western Roman Empire the Lombards settled here, as can be seen by the archaeological excavation that in the Bivio area brought back to light by the old necropolis.The layout of the town centre has an apparently typical Roman layout, but is of medieval origins.Frossasco later was owned by the abbey of Novalesa, which donated it in 1064 to the Santa Maria Cloister of Pinerolo owned by the Marchioness Adelaide of Susa.
