This type Regelbau M151 personnel bunker served as accommodation for 24 marines belonging to the Artillerie Abteilung and the Marine Funkmeβabteilung. The bunker still contains the wooden planks on which the soldiers' beds used to hang.
This barracks bunker is part of the Festung IJmuiden. Defences surrounded the Festung, consisting of a sea front, a land front and a low zone. Evidence of all of these can be found in Wijk aan Zee where over 70 bunkers are (partially) exposed or accessible in the sand.
Access to the bunker is via a long stairway upward and some distance walking through the dunes.
