SK Munition is a military bunker located in Calais, France, near the Belgian border. It is part of the extensive Atlantic Wall fortifications built by Nazi Germany during World War II to defend against Allied invasion. The bunker complex includes a Dombunker, constructed in 1940 to protect artillery pieces from aerial bombardment.
These structures were designed to withstand heavy bombing and provide secure storage for munitions and military equipment. The site is now situated on the grounds of a car manufacturer, making it a unique example of wartime architecture integrated into modern industrial use.
