History focused its sights along the coast of Normandy, France—notably Omaha, Juno and Gold Beaches—on the early morning of June 6, 1944, as American, Canadian and British troops made landfall in their first European incursion during World War II. The entire operation was termed Operation Overlord, the code name for the invasion of Normandy. The remains of the concrete structures and steel causeway of Mulberry Harbor, built by the British, can still be seen on the beach near the village of Arromanches. The Arromanches Debarkment D-Day Museum presents animated 3D scale models to help visitors grasp this exceptional harbor and its contribution to the battle—considered perhaps the single greatest innovation that ensured victory for the Allies.
