Ouvrage Flaut, Military fortification in Belvédère, France
The Ouvrage Flaut fortification contains five military blocks connected by underground galleries stretching across the western ridge of Mount Péla.
Built between 1931 and 1935 at a cost of 23.5 million francs, this fortress defended against Italian alpine troops during World War II.
The fortification exemplifies French military engineering with its advanced underground systems, including barracks, ammunition storage, and communication centers.
The site features ground-level entrance access, while combat blocks are reached through specialized shafts equipped with narrow-gauge railways for supply transport.
Each combat block operates independently with dedicated ammunition storage, rest areas, command posts, and air filtration systems protected by armored firing ports.
