High Quality Content by WIKIPEDIA articles! Ouvrage Saint Antoine was a work (gros ouvrage) of the Maginot Line's Alpine extension, the Alpine Line. The ouvrage consisted of one entry block, one infantry block and one artillery block overlooking Modane on the way to the Col du Mont Cenis. Ouvrage Saint Gobain was just to the east, up the mountain valley. 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.
