The Houlgate battery (also called the Battery de Tournebride) was a World War II German artillery battery constructed close to the French village of Houlgate in the Calvados department in the Lower Normandy region. Built into the top of a cliff, the bunker complex was created to protect the western bank of the mouth of the River Seine and was east of the Normandy landing beach Sword which it shelled. The former fire control post has been turned into an orientation table. The battery is 8 km west of the Mont Canisy battery. Read more on Wikipedia
