En route back from RAF Upwood we decided to stop by Cambridge’s Regional War Room, aka RSG4 after developing a somewhat large fascination of bunkers. I was almost not going to bother uploading this due to a lack of pictures and lack of entry at all, however as there are no reports on this place at all anyway here is what I did get along with some history on the place…
The two storey blockhouse is located in its own very secure compound at the rear of the Government offices site in Brooklands Avenue on the outskirts of Cambridge. It is surrounded by a 10ft high fence topped with barbed wire. This bunker was originally built as a regional war room identical to the one at Shirley in Birmingham but had an extension added to it later when it became RSG4.
