Origin and history
Roppe Fort, also briefly called Ney Fort in tribute to Marshal Michel Ney, is a key element of the fortifications of eastern France. Built between 1875 and 1877 according to the Séré de Rivières system, it is part of the Belfort stronghold. Located at the top of a hill near the village of Roppe, it has a drawbridge at its main entrance. In 1890, a 252-seat shed was added nearby, and in 1893 it was connected by a strategic railway to the other forts of the area.
Between 1905 and 1910, the fort underwent major modernization: a 646-seat concrete barracks was built, the capons were replaced by counterscarp chests, and machine gun turrets and a 155R turret, model 1907, were installed. During World War I, a network of 17 underground galleries was dug and concreted in the interwar period, linking various points of the fort to an underground barracks.
In the mid-war, an accident caused the explosion of the south-east counterscarp trunk, due to the ammunition stored. Although not repaired, a detached chest is built in front to defend the ditch. The fort remains used by the army to train recruits, demonstrating its long-term strategic importance.
