Ouvrage Bois-du-Four is a lesser work (petit ouvrage) in the Fortified Sector of the Crusnes of the Maginot Line. The ouvrage consists of a single large combat block without an underground gallery system and is located between petit ouvrage Mauvais-Bois and gros ouvrage Bréhain facing Luxembourg. A planned expansion never carried out was intended to enlarge Bois-du-Four into a fully equipped gros ouvrage.
