Musée du Débarquement Arromanches
Right on the seafront, this meticulously curated museum tells the extraordinary engineering story of the prefabricated Mulberry B harbour — the floating port the Allies towed across the Channel in 1944 to supply their advance into France. Through scale models, original equipment and panoramic windows framing the real harbour ruins still visible offshore, it brings one of WW2's greatest logistical
What Makes This Museum Unique
Unlike many D-Day sites that focus on the fighting, the Musée du Débarquement zeroes in on the audacious plan to build a temporary port from scratch — 600,000 tonnes of concrete caissons, floating roadways and breakwater ships, all assembled in under two weeks.
The centrepiece is a large-scale diorama showing the complete harbour layout, with recorded narration explaining how 9,000 tonnes of supplies passed through every single day at its peak.
Standing at the Windows
The museum's greatest trick is its floor-to-ceiling seafront windows: you read about the Phoenix caissons, then look up and see the rusting hulks of the very same structures sitting in the bay 80 years later.
Low tide is the best time to visit — more of the concrete caissons emerge from the water, and the scale of what remains becomes even more astonishing.
