About
Ouvrage Janus is a work (gros ouvrage) of the Maginot Line's Alpine extension, the Alpine Line, located to the east of Briançon on near the Col de Montgenèvre. The ouvrage consists of one entry block, two infantry blocks, two artillery blocks, two observation blocks and one combination block at an altitude of 2,540 metres (8,330 ft), the second highest fortification on the Alps in 1940. Built on the site of the old Fort Janus, it retained the old fort's 95mm naval guns and added two 75mm guns.
