Bletchley Park

Bletchley Park was the central site for British (and subsequently, Allied) codebreakers during World War II. It 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. Located in Milton Keynes, Buckinghamshire, Bletchley Park is open to the public, and receives hundreds of thousands of visitors annually.
