Paddock (war rooms)

Paddock is the codeword for an alternative Cabinet War Room bunker for Winston Churchill's World War II government located in Dollis Hill, northwest London under the Post Office Research Station. It was constructed in 1939 but only rarely used during the war, with only two meetings of the War Cabinet being held there. It was abandoned in 1944.

Paddock has had various, intermittent uses since (including a brief period where what is thought to be the map room was used as a Post Office social club) but otherwise the site remains largely disused as it was when it was decommissioned at the end of World War II.

The bunker is owned by the housing association responsible for the homes now occupying part of the former research station site above, and is open to the public two or three times a year, with guided tours provided by volunteers from the Subterranea Britannica organisation - see below.
