Gun Battery Landemer

Up to the start of the Second World War, the French Navy was building a gun battery they called Castel Verdon, located on a hillside 10 km. west of their important naval base of Cherbourg.
The battery was to be equipped with 2 turrets, each fitted with twin 340 mm. guns. The two gun pits, almost 20 meter deep, were virtually complete when the Kriegsmarine (German Navy) took over the construction site in the summer of 1940.
