The Atlantic Wall Museum is located inside the former German headquarters acting as fire control for the batteries covering the entrance of the Orne river and the canal connecting Caen to the sea. The 17-meter-high concrete tower has been fully restored to make it look like it was on 6 June 1944. The six floors have been recreated down to the last detail.

On the Grand Bunker’s six floors visitors may roam all its inner rooms, which have been recreated down to the last detail: generator room, gas filters room, casemate with machine gun protecting the entrance, dormitory, medical store, sick bay, armoury, ammunition store, radio transmission room, telephone switchboard, observation post equipped with a powerful range-finder and on the top floor a 360° view over the area of Sword Beach and the Bay of the Seine from Le Havre (northeast) to Quinéville (northwest).

Many photographs, documents and items concerning the construction of the Atlantic Wall, the artillery, the beach defences, etc. are presented. The Museum also offers an insight into the tactics of the shock troops specially trained for the D-Day operations against the Atlantic Wall defences, as well as the everyday life of the German Army soldiers.
