Churchill War Rooms of the Imperial War Museum
Between 1939 and 1945, several basement offices in London’s Whitehall area served as meeting places for Prime Minister Winston Churchill and his trusted advisors. Known collectively as the Cabinet War Rooms, the underground bunker sheltered Churchill during the Blitz, an 8-month-long German bombing attack on Britain. Each day, visitors can explore the rooms and learn about the people who hid in them. Admission is free.
