The municipality includes several surrounding hamlets including Nessonvaux which is where, between 1904 and 1958, the Imperia company produced automobiles. The factory building survives. This building is one of two examples of test tracks on its roof. The other known roof test track is on the roof of the old Fiat factory in Turin, Italy.
