The ouvrage consists of one and two infantry blocks at an altitude of . Gordolon was built by Borie contractors at a cost of 21.4 million francs. Work started in November 1931 and was completed in April 1934. Description. Ouvrage Gordolon was planned to control the road through Roquebilliėre in coordination with Ouvrage Flaut. Both "ouvrages" are unusual for the Alps in having anti-tank guns, which were more commonly used in main Maginot Line  in the more favorable tank country of northeastern France. The compact plan was laid out on two levels, with a planned expansion of the barracks never carried out. A fourth block was planned as a casemate with two heavy machine gun embrasures, but not built. Two observation posts included the post at Pas d'Albéras.
