The Longues-sur-Mer Gun Battery is a well-preserved German coastal artillery battery located in Normandy, France. Built as part of the Atlantic Wall defenses during World War II, this bunker complex played a critical role in the defense of Omaha Beach during the D-Day landings on June 6, 1944. The battery features four casemates housing 150mm naval guns, observation bunkers, and underground ammunition storage facilities.
Today, it stands as one of the most intact examples of German coastal fortifications in France, offering visitors a tangible connection to the D-Day invasion and the broader history of the Normandy landings.
