Underground plotting room. A deeply buried WW2 bunker accessed by a series of ladders leading approximately 10m
underground from a concrete and steel hatchway. The only surface indication that the bunker exists is the presence
of several mushroom ventilators and the steel access hatch with steel balustrade. Below the ground surface is a complex of 4 rooms with steel doors. One of the rooms contains the air-conditioning system for the bunker – electric fans, which drew in air via ventilation shafts from the surface mushroom ventilators. Within the complex is evidence of many cable conduits for power and probably telephone connections. A most of the original fittings have been stripped. The entire underground complex is surrounded by a circular tunnel with a drainage sump – a device also used on the battery shell magazines to control ground water seepage. The interior of the bunker is well preserved and the walls are painted light blue (similar to search light positions). The walls are covered in recent graffiti, much of it postdating 1994. The area is the vicinity of the entrance to the bunker appears to have once been well maintained with formal foot paths delineated with cobble stones
