The secret headquarters, from where Winston Churchill lead the British troops in the Second World War, is now a museum.
The cabinet was used from 1938 until the end of World War II, so 1945. Nowadays it is used as a museum, where there are many different exhibits related to Churchill's life on a 15m board, which tells about the different phases in Churchill's life and the events in the world at the time. You can get some idea about what it was like working underground in a maze-like environment.
The Cabinet War Rooms from World War II with its maps are also captivating, as is the secret phone room disguised as a toilet inside a storeroom. The room was where he communicated with the president of the United States of America.
