RAF Bentley Priory Operations Room – Bunker

The Operations Room at RAF Bentley Priory was so important during the Battle of Britain because it was the only place which oversaw all aerial movements above Britain. They received the information about these from the Filter Room, and also from the Observer Corps Centres. In March 1940, the work being carried out in the Mansion House was considered so essential that the Operations Room and Filter Room were moved into a newly built underground bunker to protect them from bombing.
