Ouvrage Col du Caire Gros was a lesser work (perit ouvrage) of the Maginot Line's Alpine extension, the Alpine Line. The ouvrage consisted of two entry blocks facing Italy. Additional blocks were planned but not built. Here is the list of all ouvrages of the Maginot Line, organized by sector and type of fortification. Ouvrage translates as "works" in English: published documents in both English and French refer to these fortifications in this manner, rather than as "forts". An ouvrage typically consists of a series of concrete-encased strongpoints, linked by underground tunnels.
