Bletchley Park is a stunning looking mansion established in 1877. The mansion has a massive courtyard in front of it.
Alan Turing is highly associated with Bletchley Park as he used to work there during the 2nd World War. Bletchley Park was known as the primary site for British and thereafter, for allied codebreakers during the Second World War. The Government Code and Cipher School (GC&CS) was housed by it. The task of the GC&CS was to routinely break the German naval (Kriegsmarine) Enigma messages of the Axis Powers – above all the German Enigma and Lorenz ciphers.
