The Grand Bunker of the former Command and Fire Direction Post has been completely renovated in order to house a Museum entirely dedicated to the Atlantic Wall in Normandy. After having belonged to the French Navy, the founders wanted this unique blockhouse to regain its original appearance.


A remarkable construction, since it is a Sonderkonstruktion, all the rooms were refurbished in a remarkable way, with very abundant and authentic material. The founders took full advantage of this 17-meter high construction to put into context and present the essential functions that characterized the life of the defensive positions of the Atlantic Wall facing the D-Day landings.


The founders of the Museum wanted to offer the visit the 5 levels of this blockhouse in which was installed the nerve center of the command of the defenses of the estuary of the Orne, in order to reconstruct and restore the atmosphere which could reign in this one. here on the eve of D-Day!

The Atlantic Wall

The Atlantic Wall is a system of fortifications built by the Germans during the Second World War. It runs along the Atlantic coast and stretches from northern Norway to southern France.

In 1941, the United States entered the war against Germany. Adolf Hitler fears that the Allies will organize a landing on the Atlantic coast. He then decided to strengthen the defenses of the coasts, ports and submarine bases, according to a directive of March 23, 1942. He instructed Marshal Rommel to organize the defenses which, according to him, were ineffective.

4000 km long, the Atlantic Wall required approximately 13 million cubic meters of concrete for its construction. It caused the deaths of approximately 10,000 Allied soldiers.

« Historical site to visit absolutely. The bunker is very well preserved and inside the reproduction of the different floors and the different German soldiers with their equipment is subjugating. It’s amazing how this bunker was built and how very functional and above all operational it was. I highly recommend. »

« What a immersive experience in history! A breathtaking view when you dare to climb to the last level. We realize what life could be like inside. And that feeling of invincibility against allies is also there. It’s been almost 80 years already. Beautiful restoration and site conservation. »
