At the heart of the artificial harbour,
on an amphibious boat.
A 45-minute immersive tour on board L'Archimède, an amphibious passenger boat, to discover the D-Day landing beaches from the sea and relive the experience of the heroes of 6 June 1944. Departing from Arromanches-les-Bains.
The one viewpoint no land visitor can take: that of the Allied ships, the morning of 6 June.
On board
Forty-five minutes at the heart of the remains.
L'Archimède boards its passengers directly from the slipway at Arromanches: the launch of the amphibious boat from the beach is already the first sequence of the experience. On board, 43 seats, a multilingual audioguide, and a historical narration retracing the construction of the artificial harbour and its decisive role in the landing of Allied troops.
The tour passes close to the Phoenix caissons offshore, runs along the Beetles still visible from the shore, and gives you a view from the water of the natural amphitheatre of Arromanches that framed Mulberry "B". An exclusive perspective — impossible on foot — on one of the most remarkable remains of the Second World War.
Wheelchair-accessible. French flag. Amphibious boat built in 1992 by Établissements Proteau (Aigrefeuille, Charente-Maritime), port of registry Cherbourg.
The Mulberry harbour
The one artificial harbour that held.
Two artificial harbours had been towed across the Channel in the days following 6 June. Mulberry "A" off Omaha was destroyed by the storm of 19 June 1944. Mulberry "B" at Arromanches — also known as Port Winston — remained the sole operational harbour, in continuous use until November 1944. Over its operational life, it handled in the order of 2.5 million men, 500,000 vehicles and 4 million tonnes of matériel.
Today, from the sea, you can see the Phoenix caissons at anchor, the sixteen Beetles still visible from the shoreline, and three sections of floating roadway. A reading you cannot have from the beach alone.
Our approach
Three commitments, one tour.
Amphibious boat
L'Archimède boards from the beach itself, on the slipway at Arromanches. A spectacular launch, an intimate 43-passenger format, coastal navigation under French flag with a professional crew.
Multilingual audioguide
Historical commentary in French and English delivered through headphones to respect each passenger's pace. Factual narration, sourced, no overstatement, no sound effects. A reading, not a show.
45 minutes, six daily departures
A compact format that fits inside a full memorial day at Arromanches: museum, 360° circular cinema, open-air exhibits, and the boat tour as the maritime complement.
