The museum opened in 2016 inside a former ammunition bunker (type V.F. 7a). During the war, the bunker was connected by tunnels to other bunkers to allow for the safe transport of ammunition. After the liberation, most of the bunkers in this area were sealed and covered with sand.
In 2014, the Egmond ’40-’45 Foundation undertook efforts to excavate and restore this bunker. The museum consists of two furnished rooms featuring authentic objects from the wartime period.
Through photographs and historical weapons, visitors gain an impression of the Atlantikwall at Egmond aan Zee. There is also attention to the beach obstacles and the postwar clearing of landmines by German soldiers — the latter topic is illustrated by a short film shown in one of the rooms.
