Hello there,
I am currently looking for information about the Roy Barracks in Ratingen/Germany. I have taken pictures in German buildings, unfortunately, I had problems in reaching the British ones:
http://hawks-geocaching.de/photogallery.php?album_id=151 (never mind geocaching, this was just a side effect

)
The location of this aerial is N 51° 16.497 E 006° 49.503 , and I think the Roy Barracks must be right there as well.
I would be glad about anything I can get! Unfortunately, the location is bulldosed right now as some stupid politician decided to use it for building some kind of prison

...
Best regards,
Nik
