A former German coastal artillery gun position located near the coast of Normandy, France. This site was part of the Atlantic Wall fortifications constructed during World War II to defend against potential Allied invasion. The designation 'OB' indicates it was an observation bunker, while 'Geschütz(f)' refers to a German gun emplacement, likely housing an 8cm caliber coastal defense weapon.
Such positions were strategically placed along the French coastline to control sea approaches and provide fire support for defending forces.
