Fort de Corbas, Fort in France

Fort de Corbas is a military fortification in the French town of Corbas, built between 1878 and 1880. The structure features thick walls, a rotating Mougin turret with two cannons, and underground tunnels designed to defend against attackers.

The fort was built as part of the Séré de Rivières system, a network of fortifications designed to defend the Lyon region in the late 19th century. It was officially abandoned in 1998 and is now used by the French Ministry of the Interior as storage.

The fort is named after the commune of Corbas, where it stands at 210 metres altitude between the forts of Saint-Priest and Feyzin. Its pale stone facade with the "FORT DE CORBAS" sign above the central arch is the element residents and passers-by most readily recognise. Since 1998 the site has passed from the army to the Ministry of the Interior.

The fort stands at 210 metres altitude between the forts of Saint-Priest and Feyzin, and the army left it in 1998. It passed to the Ministry of the Interior as an explosives depot, so the interior is not open to visitors. From outside, the pale stone facade with its central arched tunnel and the metal footbridge leading to it can be seen from the grassy slope.

The fort is the only installation in this region with a rotating Mougin turret, a gun tower from 1876 that could mount two large cannons. This innovative weapons technology was remarkably advanced for the time of its construction.
