This bunker has considerable damage on the outside. This damage was not caused by grenades or rockets, but by a test explosion when there were plans to demolish the bunker.
On the walls of the bunker are descriptions of the ammunition that used to be there. Those were not ordinary grenades, but lighting grenades. This illuminated the target, which could then be attacked with other ammunition. This bunker was reused by the Dutch army during the Cold War.
Please note!: The bunker is located in the dunes of beach Koudekerke. To reach the bunker you have to climb a staircase and walk through the dune sand.
