The Princess Mary's Royal Air Force Hospital Halton, was the first Royal Air Force hospital to be built that was dedicated to air force personnel. Located on what was then the largest of the RAF camps at RAF Halton in Buckinghamshire, England, the hospital treated over 20,000 patients during the Second World War and was the first place in the world to use penicillin on a large-scale. The hospital continued in use throughout the Cold War, only closing in 1996 due to defence cuts.
