Bunkerinfo
The bunker is located on the grounds of the Beeckestijn estate and is of type 502. Several bomb-proof bunkers were built on the estate to accommodate the soldiers whose job was to guard the passage to the fortress at Walzkörpersperre number 108. Nowadays, the bunker can no longer be entered and is largely hidden under a mountain of sand. Only a small part of the entrance side and the Tobruk are visible.
