Louis Joubert Lock

The Louis Joubert Lock measures 350 meters in length, 50 meters in width, and 15 meters in depth, enabling access to large vessels in Saint-Nazaire port.

Built between 1929 and 1933, the lock became the primary target of Operation Chariot in 1942 when British forces prevented German warships from using its facilities.

The lock represents the industrial legacy of Saint-Nazaire, serving as a fundamental element in the development of French naval construction and maritime trade.

The structure functions both as a lock for ship passage and as a dry dock, allowing maintenance work on submerged parts of vessels when drained.

The facility received a new 1,280-ton gate in 2010, measuring 50 meters long and 17 meters wide, to maintain its essential maritime operations.
