Bletchley Park was a large house which was split up into different sections containing people with different skills of code breaking. Bletchley Park was setup to receive messages from German operators that had been picked up by wireless stations in Britain. These listening posts were called the Y service, they then conveyed the messages to Bletchley Park otherwise known as station X.
Bletchley Park began by revolving around two huts. One being Hut 6 which received signals and messages and attempted to decode them, the people working in hut 6 were Cryptanalysts/code breakers. They turned them into complete texts, a few words or sometimes just a few letters. The messages which had been decoded by hut 6 were sent by means of a wooden tunnel to hut 3 they were pushed through the tunnel with a broom handle. The people in hut 3 were intelligence officers and linguists, whose job it was to identify possible German words from mere letters or scraps of text sent from Hut 6.
