D-Day Museum, World War II museum in Arromanches-les-Bains, France.

The D-Day Museum is a military history museum in Arromanches-les-Bains dedicated to the Normandy invasion. It displays uniforms, weapons, photographs, letters, and films that explain how the operation unfolded and what soldiers experienced.

Built on the initiative of Raymond Triboulet, the museum was inaugurated on 5 June 1954 by President René Coty, making it the first museum created to commemorate the Normandy landings. Its architect, François Carpentier, later became mayor of Arromanches in 1963. It stands facing the beach where the artificial harbour Mulberry B was assembled from June to August 1944 to supply Allied troops.

The museum was built on the initiative of Raymond Triboulet and inaugurated on 5 June 1954 by President René Coty, the day before the tenth anniversary of the landing. It was the first museum created to commemorate the Normandy landings. Its architect, François Carpentier, became mayor of Arromanches in 1963.

The location sits right by the coast with views of the artificial harbor structures and remnants still visible. Most visitors need about 2 to 3 hours to see the exhibitions and explore the site itself.

The museum stands on the esplanade facing the beach where the artificial harbour was sunk. Its wide windows look out on the remains of Mulberry B, a semicircular harbour of about 500 hectares formed by 115 concrete Phoenix caissons, old ships and three landing bridges, operational from early July 1944 despite an eight-metre tide.
