About Cherbourg Roadstead
The Rade de Cherbourg is the world's second-largest artificial harbor, covering 1,500 hectares of protected water. Construction began in 1783 under Louis XVI and took over 100 years to complete, with Napoleon envisioning it as a strategic naval base against Britain. The main breakwater stretches 3,750 meters, featuring three 19th-century forts now classified as Monuments Historiques.
In 1786, King Louis XVI made his only provincial journey as monarch specifically to witness the sinking of the ninth cone during construction. The initial engineering approach used 90 massive conical wooden structures filled with stones, but the first four failed during storms, leading engineers to abandon this method entirely.
