Paddock

Paddock was the code name given to the standby War Rooms in Brook Road, Dollis Hill, London built at the start of WW2. It appears to have been only used twice as Churchill was not fond of it.

The bunker can clearly be seen in Brook Road & sits close to the Post Office Research Station where Colossus, the codebreaker, was designed by Tommy Flowers in 1943. Paddock was built underneath this site.

The blip is of the entrance to Paddock.
