Mill Hill Regional War Room
This bunker was one of the four London group controls (regional war rooms). It covered the North Group (Barnet, Camden, City of London, Enfield, Haringey, Islington, Westminster).
It became disused in 1958 and remained so. It was to be used by Barnet as their emergency control but they never used it. Only one room contained comms equipment.
It is now an overgrown and derelict site. It is a good example of one of the one-level RWR’s but is very difficult to access and the military police from the adjacent Army site are not hospitable!
