Bletchley Park

Cribbing from Wikipedia: 

Bletchley Park is an English country house and estate in Bletchley, Milton Keynes (Buckinghamshire), that became the principal centre of Allied code-breaking during the Second World War. The mansion was constructed during the years following 1883 for the financier and politician Herbert Leon in the Victorian Gothic, Tudor and Dutch Baroque styles, on the site of older buildings of the same name. During World War II, the estate housed the Government Code and Cypher School (GC&CS), which regularly penetrated the secret communications of the Axis Powers – most importantly the German Enigma and Lorenz ciphers. The GC&CS team of codebreakers included Alan Turing, Harry Golombek, Gordon Welchman, Hugh Alexander, Bill Tutte and Stuart Milner-Barry.

We had talked a few times about visiting Bletchley as it is within our sphere of interest and finally got around to it on the way home from an air show weekend. The place is indeed very interesting giving the history of code breaking activities, initially within the mansion but then into numerous huts built in the grounds. The people that worked here were sworn to secrecy and many died without ever speaking of their wartime activities, not even to their families. First hand stories and displays, in many original huts, now recount what went on at Bletchley and how it helped the Allied war effort and, ultimately, led to the first real computer. Certainly worth a visit.
