This was the central site for Britain's codebreakers during World War II. Run by the Government Code and Cypher School (GC&CS), it regularly penetrated the secret communications of the Axis Powers – most importantly the German Enigma and Lorenz ciphers. The official historian of World War II British Intelligence has written that the "Ultra" intelligence produced at Bletchley shortened the war by two to four years, and that without it the outcome of the war would have been uncertain.
This was the second site (after a fail) on an awesome road trip with @CuriousityKilledTheCat, Sprinks and a couple of non OS members.
After seeing reports on this before we went this was one place I really wanted to see because of the amount of history it held, and the role it played during the second world war....
when we pulled up, it wasn't looking promising because the block was boarded up to high hell, but we'd managed to get in...
We spent quite a while in here, exploring the never ending corridors & amazed by the piles of equipment from computers to radios to decibel readers.
definitely an explore to remember!
Thanks For Looking
