Origin and history

The artillery battery of the Roule is part of a fortified ensemble built on the Roule Mountain in Cherbourg-en-Cotentin. Initially, the site houses a hermitage founded in 1650, replaced by a dread in 1793 to protect the harbour from British attacks. The current fort, built between 1853 and 1857 under Napoleon III, was subsequently modernized by the National Navy in 1928 with storage tunnels.

During the Second World War, Todt transformed the site into the Atlantic Wall. The Germans dig 750 metres of underground galleries, install four 105 mm cannon casemates and a fire direction post. These developments, which were carried out from 1942 onwards, were designed to defend the Cherbourg harbour. The fort was taken over by the Americans on 26 June 1944 after a German occupation started in 1940.

After the war, the National Navy re-used the site as a command post until 1988 and then as a communications centre. Part of the facility also houses the School of Military Applications for Atomic Energy. Since 1954, the summit fortifications have hosted the Cherbourg Liberation Museum. The German battery, with its galleries, was listed as a historical monument in 1995, bearing witness to the military history of the 20th century.

The site illustrates the historical stratifications of the Roule: from the 17th century religious origins to the French fortifications of the 19th century, to the German developments of the Second World War. Today, it combines military memory and architectural heritage, with spaces partially open to the public.
