High Quality Content by WIKIPEDIA articles! Ouvrage Saint Roch was a work (gros ouvrage) of the Maginot Line's Alpine extension, the Alpine Line, also known as the Little Maginot Line. The ouvrage consisted of one entry block, one artillery block and two observation blocks overlooking Sospel. 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.
