The Fort de Queuleu is a fortification to the southeast of Metz, near Queuleu, France. Construction began while part of Lorraine was under French rule in 1868. After the interruption of the Franco-Prussian War of 1870-71, the fort was improved between 1872 and 1875 by the German Empire, which had annexed the area as a result of the war. Renamed Fort Goeben, it formed part of the first ring of the fortifications of Metz. Functionally obsolete by the First World War, it saw no military action, but was used by the Germans as a detention center for members of the French Resistance during World War II.
