Batterie d’artillerie côtière d’Auderville-la-Roche, located in La Hague (Manche), is a fort. The monument is currently closed to visitors.
A striking vestige of the Atlantic Wall, the "Stahl" battery at Auderville-la-Roche dominates the tip of La Hague with its bunkers camouflaged with Asbest, a rare material combining straw, asbestos and rubber.
Perched on the edge of the Cap de la Hague, where the English Channel meets the Atlantic, the German "Stahl" coastal battery is one of the best-preserved World War II fortifications on the Normandy coast. Twenty-four reinforced concrete structures - casemates, troop shelters, fire direction posts - rise up from the grassy plateau like so many mineral witnesses to a shocking era, listed as a Historic Monument since December 2024. What immediately sets the site apart is its unique camouflage. Several of the structures, including the Leitstand, are covered in an exceptional coating of Asbest - a mixture of straw, asbestos, rubber powder and cement - designed to fool Allied aerial reconnaissance. This technique, extremely rare on the Atlantic Wall, gives the structures an organic, almost living texture, oscillating between natural rock and industrial material. The visitor experience is both intimate and breathtaking. Visitors wander between the open-air recesses that housed the recovered French cannons, explore the thickly vaulted ammunition bunkers and enter the fire direction station, whose upper tank once housed a precision telemeter. The ghostly presence of the Seetakt FuMO2 radar - whose locations are still visible in the masonry - is a reminder of the technological sophistication deployed here. The natural setting amplifies the emotion: the low-lying, windy moors of La Hague, the jagged cliffs plunging into the ever-changing sea, and the clear horizon as far as the Channel Islands make for a breathtaking panorama. The solitude of the site, far from the main tourist routes, preserves an atmosphere of authentic contemplation that lovers of military history and photographers will particularly appreciate.
The 'Stahl' battery is a perfect example of the German army's standardised fortification doctrine, based on the Regelbau (regulatory construction) plans drawn up by the Todt Organisation. The complex is made up of twenty-four structures spread across the plateau: circular open-air recesses for artillery pieces, vaulted ammunition bunkers of the Regelbau 134 and Vf7a types, barracks shelters of the 621 and 622 types with concrete walls over a metre thick, and the Regelbau 636 fire direction post, the architectural centrepiece of the site. This two-storey Leitstand incorporates a number of specialised tanks: a close defence tobrouk at the top, an upper tank for the rangefinder, and a front location dedicated to the Seetakt FuMO2 radar. The most remarkable technical feature is the Asbest coating applied to several of the structures. This composite material - a mixture of chopped straw, asbestos, powdered rubber and cement - was sprayed onto the outside walls to break up the reflections characteristic of raw concrete and create an irregular texture imitating the natural ground. Extremely rare on this scale of preservation on the whole of the Atlantic Wall, this coating today provides unique evidence of the sophisticated camouflage techniques deployed by German military engineers in 1943-1944. The four Regelbau 679 casemates, left unfinished, present the concrete skeletons of an interrupted construction, an architectural document of irreplaceable historical value.
