Origin and history
The Monts-Trottins artillery battery is a military installation located in the commune of Fontaine-la-Mallet, Seine-Maritime department, Normandy. Built between 1942 and 1943, it belonged to the defence of the Fortress of Le Havre and the Atlantic Wall. Its infrastructure included encumbrances, a modified R 607 ammunition shelter, a R 646 well shelter, and an R 669 artillery casemate. It was positioned about 1 km behind the Octeville-Montivilliers defence line.
During World War II, this battery was a key element of German defences on the Normandy coast. It was taken on September 11, 1944 by the 51st Scottish Division, marking an episode of the region's liberation. After the war, all remaining surface and underground elements were listed as historical monuments by order of 28 October 1996, thus recognizing their heritage value.
Today, the Trottin Mountains battery bears witness to the German military architecture of the Second World War. Its inscription as a historic monument preserves this vestige of the Atlantic Wall, while offering a place of memory linked to the liberation of Normandy. The structures still visible, such as casemates and shelters, illustrate the fortification techniques used during the conflict.
