Origin and history
The anti-aircraft battery of Auderville-la-Roche and La Valette, located in the commune of La Hague in the Channel, was built by the Luftwaffe during the summer of 1940 as part of the German occupation. This strategic site, known as the Ammer station, combined advanced technologies for the time: two Freya Fu.MG radars (models 450 and 401) and two Würzburg Reise Fu.SE 65 radars, supplemented by Flak guns installed in encuments. The equipment was designed to protect two nearby artillery batteries, the Stützpunkt 351 (Alderville Hague) and Stützpunkt 356 (Alderville Laye), while providing radar and anti-aircraft coverage along the Normandy coast.
The military complex also included logistical infrastructure and shelter for soldiers, including three Regelbau 622 (standardized bunkers). In total, 23 elements constituted the site, including cantonment buildings and remains now protected as historical monuments. The official inscription by order of 23 December 2024 covers works in elevation or buried, as well as associated parcels, with the exception of a modern dwelling located nearby.
This site illustrates the fortification effort of the Atlantic Wall by Nazi Germany, with a rare concentration of radar and air defence technologies on the same site. The remains, still visible, bear witness to the military strategies of the Second World War and the occupation in Normandy, where the German presence marked the landscape and local memory.
The location of the site, along the coast, reflects its key role in monitoring maritime approaches and protecting against allied air raids. Today, these remains provide historical insight into the electronic warfare techniques and military infrastructure of the time, while constituting a memorial heritage of the Resistance and Liberation in Lower Normandy.
