Bentley Priory is indeed owned by MOD and was purchased by the then Air Ministry in 1926. Formerly the home of Lady Emma Hamilton ("special friend" of Lord Nelson) and Queen (?) Adelaide, it has equal historical value to both the RAF and the RN. Most of the interior of the old building is in fact a (fake) reconstruction as the Mess burnt down during refurbishment in the late 70s/early 80s. It should be kept for it's historical value alone; however, if the RN can return Greenwich to it's owners, then the RAF can sell Bentley Priory (at a vast profit !). I hope I am wrong, but big money talks.........
