Arsenal de Rochefort

The Arsenal de Rochefort was a French naval base and dockyard in the town of Rochefort. Founded in 1665, it was closed in 1926.

In December 1665, Rochefort was chosen by Jean-Baptiste Colbert as a place of "refuge, defense and supply" for the French Navy. Its military harbour was fortified by Louis XIV's Commissary of Fortifications Sébastien Le Prestre de Vauban. Between 1666–1669 the king had the "Corderie Royale" (then the longest building in Europe) constructed to make cordage for French ships of war. The making of cordage ceased in 1867, and in 1926 the Arsenal de Rochefort was closed.
