RAF Bentley Priory

 Second World War 1939-1945, former air force base

RAF Bentley Priory was a non-flying Royal Air Force station near Stanmore in the London Borough of Harrow. It was famous as the headquarters of Fighter Command during the Battle of Britain and the Second World War. The RAF Bentley Priory site includes a Grade II* listed Officers' Mess and Italian Gardens. These, together with the park are designated a Registered Garden Grade II.
Originally built in 1766, Bentley Priory was significantly extended in 1788, by Sir John Soane, for the First Marquis of Abercorn. The priory was the final home of the Dowager Queen Adelaide, queen consort of William IV, before her death there in 1849. It subsequently served as a hotel and girls' school before being acquired by the Royal Air Force in 1926.
The Royal Air Force station role ceased on 30 May 2008, following the relocation of units to their new accommodation at RAF Northolt and the site will be used for private accommodation and the Officers' Mess will become a Battle of Britain museum
