  • An actor portraying General Ismay in the immersive theatrical event Operation Black Door at Churchill War Rooms


    Big decisions come with big diplomatic consequences. Every act counts as you unpick one of the most difficult decisions we had to take against one of our closest allies. What will be the cost to ensure survival?

  • An actor playing Joy Hunter in Operation Black Door at Churchill War Rooms


    Infiltrate the offices of the war rooms typists and switchboard operators. Those with privileged access to strategic information, to uncover the puzzle of the missing ships, and all those souls on board. What are we protecting?

  • An actor playing Delmar in Operation Black Door at Churchill War Rooms


    Total war is not just waged between two armies but between the hearts and minds of two populations. Everything is in question as you unravel who is behind the propaganda radio network, who they work for, and how did we get a U-Boat without a fight? 

  • An actor plays Nicholson in Operation Black Door at Churchill War Rooms


    Make sure you have a stomach for confrontation as we send you to gather information on the heart-wrenching choices that were made to allow the British rescue effort from Dunkirk. What sacrifices had to be made for the greater good? 

  • An actor plays the part of a cabaret singer in Operation Black Door at Churchill War Rooms


    All is not what it seems. An unidentified body and falsified strategic documents have been discovered. We need you to uncover the hidden goings on of a mission so mad that it may just have tipped the balance of the war itself. What will you uncover?

London's Secret War Rooms

During the Second World War, a group of basement offices in Whitehall served as the centre of Britain’s war effort. The complex, known as the Cabinet War Rooms, was occupied by leading government ministers, military strategists, telephonists, secretaries and prime minister Winston Churchill.

Following the devastation of the First World War, military planners feared up to 200,000 casualties from bombing in the first week of a future war.

Plans to evacuate the prime minister, cabinet and essential staff from London were drawn up as early as the 1920s. However, concern that Londoners would feel abandoned if the prime minister and government were in a safe place and issues about the speed of evacuation, led to a search for an emergency shelter in central London.

In June 1938 the New Public Offices building was selected. It was near Parliament, with a strong steel frame and a large basement.

Only a few, specially chosen people knew its secrets...until now.

The immersive storytelling is inspired by real life stories, experienced and lived through by staff at Churchill War Rooms during the Second World War. Find out more about the real history behind Operation Black Door.
