The municipality includes several surrounding hamlets including Nessonvaux which is where, between 1904 and 1958, the Imperia company produced automobiles. The factory building survives. On the roof cam be seen the test track. This is one of just two test tracks on the roof of a car factory, the other (better known) one being on top of the old Fiat factory in Turin.
