The last occupants of Arnhem Bks were RHQ 4 RMP. They moved out in October 2008, at which point the top end of Monty Lines (up the hill from the guardroom) was secured pending demolition. All the windows have now been boarded up and the footbridge over the A325 demolished.
The last scene of the Quantam of Solace was filmed in the blocks between Normandy Bks and the A325.
Supposedly it will get handed back to the local council at some stage....... I hear that they want to put 4000 houses there !!! Mostly all boarded up now, but a couple of blocks are still being used as accommodation by some catering people. I remember pre 1972 when there was no "wire" around the camp..... how times change.
The whole Garrison will drastically change by 2014.
