During the Second World War, Bletchley Park was the site of the United Kingdom’s main decryption establishment, the Government Code and Cypher School (GC&CS), where ciphers and codes of several Axis countries were decrypted, most importantly the ciphers generated by the German Enigma and Lorenz machines. The place was known as “B.P.” to the people who worked there.
