Supplementary fire control bunker
Small bunker; it was supposed to be in command of the 38 cm battery if the large fire control bunker should cease to function in consquence of combat.
The walls and ceilings of the bunker are 80 cm thick; 120 cubic metres of reinforced concrete were used. It is unknown when the bunker was built; probably not before the summer of 1942.
The bunker has two rooms; both have an observation slit. Little space was left for equipment in the small bunker.
