From Wikipedia, the free encyclopedia.
The Cabinet War Rooms are a former bunker in Whitehall in London, close to the heart of the United Kingdom government. They were in the basement of the Office of Works, between Number 10 Downing Street and the Palace of Westminster.
Construction began in June 1938, under the premiership of Neville Chamberlain, and it became operational on August 27, 1939, a week before the outbreak of the Second World War. It was shut after V-J Day. It was opened as a museum in 1981.
