The National Museum of Computing is an independent trust with its own admission fee and separate entrance from the rest of Bletchley Park. The museum traces the history of computing and includes working reconstructions of the Turing-Welchman Bombe that broke Enigma and Tommy Flowers’ Colossus that broke the Lorenz cipher, used by Hitler to communicate strategic messages with his High Command. Housing the world’s largest collection of working historic computers, the Museum enables visitors to follow the development of computing from the ultra-secret pioneering efforts of the 1940s through the large systems and mainframes of the 1950s, 60s and 70s, and the rise of personal computing in the 1980s and beyond.
