The Cité de la Mer in Cherbourg is a unique oceanographic park, housed in a historic Art Deco building, the former Gare Maritime Transatlantique. It offers an educational journey through interactive exhibits on the conquest of the oceans, including the nuclear submarine Le Redoutable, the “Titanic, return to Cherbourg” exhibition, and various deep-sea diving machines. In addition, the abyssal aquarium, the deepest in Europe, enriches the experience with its 1,000 species of fish. For an in-depth tour, visit their official website.
