In the former submarine base, 3,700m/12,139ft² are now an exhibition area devoted to the Golden Age of transatlantic liners including vessels such as the Île de France, Normandie and France. The tour is designed like a cruise: "travellers" can explore the cabins, engine rooms, immigration hold and steerage, captain's bridge and the luxurious dining room at their own pace. For those who are not afraid of capsizing at sea, an emotion-packed finale awaits you at the end!
