RAF Nocton Hall and US Military Hospital, Lincolnshire
This 400m long corridor forms part of an old hospital last used by US military stationed in the UK during the first Gulf War (Operation Desert Storm). The site was loaned to American forces in 1984 as a site to treat injured soldiers flown back from Iraq. However the war was a success and only 35 patients were treated there. The site was handed back to the UK in 1995 and remains to this day in a derelict state.
