The Fort d'Uxegney, or Fort Roussel, is part of the fortifications of Épinal. It was built near the village of Uxegney between 1882 and 1884, and was modernized in 1910. It is an example of a Séré de Rivières system fortification. It retains its armament and is maintained as a museum.
Located 6 kilometres northwest of Épinal, the Fort d'Uxegney is part of a 43-kilometre line of sixteen major fortifications designed to bar the advance of a German army into France. It retains a functioning example of an eclipsing Galopin turret. Armed with a 155mm gun, the assembly weighs 250 tons and was installed in 1907. A considerable amount of the fort's equipment remains in place, including kitchens, living facilities and details of armament, in an unusually good state of preservation.
