This German position in the west of The Hague was containing three fortifications with walls and roofs of two meters of reinforced concrete.
The biggest of the fortifications was a V143-pillbox which contained the equipment of a mammut-radersystem. The pillbox itself also had the role of being the fundation of the huge antenna which was build on top of the bunker.
