Bletchley Park was the home of the top-secret code breakers of World War Two, whose work had a profound impact on the war; it has been claimed that their success in intercepting enemy signals and breaking codes shortened the war by two years. For years, very few people knew about their work, most famously centred on German Enigma cipher machines, but information started to become more available in the 1970s. Bletchley Park was in a poor state when taken over by Milton Keynes Borough Council in 1992. A trust was set up to conserve the site and turn it into a museum and it opened its doors to the public in 1993. A massive restoration project took place and BP is now a major tourist attraction.
Bletchley Park also includes the National Museum of Computing and has featured in several films and TV productions.
