Ouvrage La Moutière is a lesser work (petit ouvrage) of the Maginot Line's Alpine extension, the Alpine Line at an altitude of 2440 meters. The ouvrage consists of one entry block, one infantry block and one observation block, with an unarmed exit block. The ouvrage supported the Ouvrage Restefond on the crest of the pass, guarding its southern flank. It also covered the Col de la Barcelonnette to the north. The position was built between 1931 and 1935.
