Le Grand Bunker is a former German fire-control post situated in Ouistreham, restored to represent its operational state during the D-Day landings. The structure is a five-story concrete fortification that served as the nerve center for the Atlantic Wall defenses in the sector. Visitors navigate through meticulously recreated rooms, including the generator room, armory, and communication center. The museum contains original radio equipment, uniforms, and documentation detailing the tactical role of the bunker during the Allied invasion. It is one of the few Atlantic Wall bunkers that has been fully preserved and restored for public access. The tower offers views over the Pegasus Bridge sector and the wider Normandy coastline. The museum occupies the original concrete shell of the 'Groß-Bunker' which was captured by the British 1st Special Service Brigade on June 6, 1944. Its strategic position was essential for directing coastal artillery fire against approaching naval forces.
