It is 2.5 miles (4.0 km) southeast of the site of RAF Woodhall Spa, in the civil parish of Tattershall Thorpe.
Built in 1940 during the Second World War, the site included Officer, Sergeant and Airman messes, a NAAFI building, ration store, latrines and ablution blocks.
It was the Trust's plan to demolish the buildings that resulted in the formation of the Thorpe Camp Preservation Group to restore the site and create a Visitor Centre.
In 1994 the Visitor Centre opened to the public with a donation entry fee and a very limited area to view.
The visitor centre commemorates both the Royal Air Force, and RAF Woodhall Spa history, as well as civilian life in Lincolnshire in the 1940s.
Famously Wing Commander Gibson took off on his final Journey from RAF Woodhall Spa with Squadron Leader Jim Warwick.
