Where did Churchill give his radio broadcasts during WWII?

Churchill delivered his iconic radio broadcasts from the Cabinet War Rooms, which served as the underground headquarters of the British government during WWII. This location was essential for communication with the public, as it allowed the government to operate securely and out of reach of enemy bombings. The broadcasts aimed to boost morale and provide information during the war, fostering a sense of unity and resilience among the British people in a time of crisis. While other locations listed have historical significance, they were not the primary sites for Churchill's radio communications during this pivotal moment in history.
