The bunker under Whitehall where the War Cabinet met, locked up in 1945 and left exactly as it was.

These are the rooms under the Treasury from which Britain ran the Second World War. Converted from a basement in 1938, when the Air Ministry expected bombing to cause 200,000 casualties a week in London, they came into use on 27 August 1939, a week before war was declared, and the War Cabinet met here 115 times, the last on 28 March 1945. Churchill, taking over in May 1940, looked at the Cabinet Room and said: “This is the room from which I will direct the war.” A slab of concrete up to five feet thick was poured over the complex during the Blitz and it grew to three times its size; staff slept in dormitories under it, the ceilings were low, the lavatories were chemical and the mice were everywhere.
When Japan surrendered in August 1945 the doors were locked and the rooms left as they stood, so what you walk through is not a reconstruction. The Map Room, staffed round the clock by officers of all three services to brief the King and the Prime Minister each morning, still has its pins in the charts. The Transatlantic Telephone Room, behind a door with a lavatory lock so that staff took it for the Prime Minister's private toilet, connected Churchill to Roosevelt through a scrambler so large it filled a basement under Selfridges. His bedroom is here, though he rarely slept in it. The rooms opened to the public in 1984, and a museum of Churchill's ninety years was added beside them in 2005.
