Buried within the north eastern section of the infilled ditch of the L19thC Fort Farningham, is an underground bunker, constructed by the Royal Observer Corps in the 1960's. The Monitoring post formed part of the UK's Warning and Monitoring Organisation to record the location, height and power of nuclear explosions and their fallout. The surface monitoring devices have been removed, only the air ventilator and the access shaft are visible, but it is likely that the internal fitting designed for the crew of three remain.(Scheduling List)

Interior is clean but flooded to a depth of 4"(1)
