In large fenced compound on South side of Canterbury Road (A253)
LOCKED Externally in good condition, the concrete is unpainted and the metal is black. A metal dome on the ventilation shaft indicates this was a master post. When inspected in 1997 the hatch was open but it is now locked. Internally much remained including tables, cupboard, shelf, wiring, some telecommunications equipment, girlie calendar! post log and a mass of papers some of which has been taken to the museum in Gravesend.
