Ouvrage Les Rochilles is a lesser work (petit ouvrage) of the Maginot Line’s Alpine extension the Alpine Line in the high Alps about 20 kilometres (12 mi) southwest of Modane. The ouvrage consists of one entry block two infantry blocks and one observation block. Unusually it was built by the Main d’Oeuvre Militaire (MOM) rather than CORF (Commission pour l’Organisation des Régions Fortifiées) which built most of the larger positions. The design was by CORF.
