The Battle of Britain Bunker, located in Uxbridge, England, is a historic underground operations room that played a crucial role during World War II. This secret command center was used by the Royal Air Force (RAF) Fighter Command’s No. 11 Group to coordinate air defenses during the Battle of Britain in 1940. From here, RAF officers directed fighter squadrons against incoming Luftwaffe attacks, making it a pivotal site in Britain’s defense.
