What is Churchill War Rooms famous for?
Churchill War Rooms is best known as the place where Britain's Second World War was directed, including the defence of London during the Blitz and the coordination of D-Day. Two details stand out for most visitors: the Map Room, abandoned in 1945 and left almost exactly as it was, with the original wall maps and the pin-marks of Atlantic convoy positions still visible and the Transatlantic Telephone Room, disguised as Churchill's private lavatory, where he used a SIGSALY-encrypted line to speak directly to Presidents Roosevelt and Truman in Washington.
What to See at Churchill War Rooms
Churchill War Rooms lets you walk through the original wartime rooms where work carried on underground throughout the bombing. The visit threads through narrow corridors and chambers where the original maps, communications equipment and everyday objects are still in place.
The Cabinet Room is where Churchill and his ministers met during the war. It has been preserved in its original state, with the chairs and papers around the table bringing the atmosphere of wartime decision-making to life.
The Map Room was the operational nerve centre, where troop movements were tracked across the maps. The maps, pins, markings and telephones are still in place, and the room has barely changed since 1945.
The complex also includes communications rooms, typing rooms, a kitchen and the staff bedrooms, giving a sense of daily life underground. One of the most distinctive details is the secret telephone room disguised as a toilet, Churchill's direct line to the President of the United States.
History of the Churchill War Rooms
Churchill War Rooms was built in Westminster beneath what is now HM Treasury, just before the outbreak of the Second World War. The site was chosen because it was close to the main government buildings but offered shelter from bombing.
The rooms became operational on 27 August 1939, a week before war was declared, and were reinforced with concrete during the war as protection against air raids. From here, Britain's wartime operations were directed, including defence during the Blitz and the later campaigns in Europe.
When the war ended in 1945, the rooms were closed and left almost untouched. They opened to the public on 4 April 1984, and the dedicated Churchill Museum was added on 11 February 2005. The site is now run by Imperial War Museums, alongside sister sites including the main IWM London and HMS Belfast.
The Churchill Museum
The Churchill Museum sits alongside the War Rooms and forms a central part of the visit. It focuses on the life and career of Winston Churchill. Its centrepiece is a roughly 15-metre interactive timeline that ties his personal milestones to world events. The displays include letters, photographs, personal objects, and audio recordings that highlight his wartime role and his wider political career.
How Long to Spend at Churchill War Rooms
Allow roughly 1.5–2 hours. You move through the rooms at your own pace, and the audio guide included with admission explains the background and use of each space.

Churchill War Rooms Tours
Guided tours run on selected dates, focusing on the history of the rooms and how they were used during the war. They add background and detail you might miss on a self-guided visit.
Is Churchill War Rooms Worth Visiting?
Churchill War Rooms is one of London's most significant museums, but the experience is unlike most other attractions. The rooms are narrow, low-ceilinged and partly dimly lit, which creates an unusually authentic atmosphere. This isn't a recreation, it's the place where wartime decisions were actually made.
What stands out is how little has been changed. The maps, telephones and room layouts are almost exactly as they were left in 1945, so the visit feels more like stepping into a preserved historic space than touring a traditional museum.
It's especially well-suited to anyone interested in history, politics or the Second World War. It isn't the most visually spectacular museum in London, but it's one of the most important.
Practical tips and accessibility
Non-flash photography is allowed in most areas. Weekday mornings are usually the quietest time to visit.
Step-free routes cover most of the site via a lift, but some original WWII corridors are narrow, and the gift shop and cloakroom are tight. Check the IWM accessibility page before you go for the current detailed route.
