Ouvrage La Déa, also known as the Petit Ouvrage de la baisse de la Déa, is a lesser work (petit ouvrage) of the Maginot Line's Alpine extension, the Alpine Line. The ouvrage consists of two entry blocks and one observation block facing Italy at an altitude of 1777m (5,830feet), armed with one observation cloche and one machine gun embrasure. The ouvrage was manned by 81 soldiers in 1940, and commanded by sous-lieutenant Guillemin.[1] The position was sited to control the Maglia valley. A fourth block with three machine gun positions was not built.[2]
