The Espadon was the first French submarine to surface at the North Pole in 1964.
The vessel could remain submerged for several weeks at a time during its active service.
It contains a total of 10 torpedo tubes.
The internal layout is original, including the narrow crew bunks and the galley area.
The submarine was decommissioned in 1985 before being moved to its current location in 1987.
The Espadon is a Narval-class submarine launched in 1957, now permanently moored in a reinforced concrete lock in Saint-Nazaire. It served in the French Navy for 27 years, completing missions across the Atlantic and under the Arctic ice. The vessel measures 78 meters in length and displaced 1,600 tons while submerged. Visitors explore the vessel through a self-guided audio tour that covers the torpedo rooms, the engine room, and the command center. The submarine remains in its original configuration, offering a look at Cold War-era maritime technology. It is docked within the historic Saint-Nazaire submarine base, a massive fortified bunker built during World War II.
