This historically significant site was the secret heart of Britain’s wartime air defence. It was here that the battle of Britain was observed, planned and controlled by ordinary men and women doing extraordinary things. You too can stand in rooms where Churchill and King George VI watched the RAF plotters and controllers tirelessly coordinate the crucial defence of the nation. Today, the original operations room appears exactly as it did at the height of the battle of Britain on 15 September 1940 at 11.30am. See genuine artefacts from the battle of Britain and beyond. Test your skills identifying aeroplanes. The story of the people behind the innovation and the politics that shaped this invention is told for the first time.
