About us

Mission Statement of The National Museum of Computing

To bring to life the history and ongoing development of computing for inspiration, research, learning and enjoyment for the benefit of general and specialist publics of all ages.

  • In support of this we acquire, conserve, restore and reconstruct historic computing machinery for preservation, display, demonstration and research.

  • Emphasis is on British computing heritage and on ongoing British contribution to innovation and development.

  • Our distinctive approach is engagement through the display and demonstration of working historic systems.

We provide context through active education programmes, festivals, lectures, visitor activities, and interpreted exhibition and interactivity to raise awareness and inspire future generations of computer scientists, engineers and inventors.

The National Museum of Computing

TNMOC is an independent trust with its own admission fee and separate entrance. It 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.

The museum runs a highly successful Learning Programme for schools and colleges and promotes introductions to computer coding amongst young people, especially females, to inspire the next generation of computer scientists and engineers.

Our relationship with the Bletchley Park Trust

The National Museum of Computing operates independently of the Bletchley Park Trust. TNMOC is an independent registered charity responsible for its own fund raising, sponsorship and management. It has its own separate entrance located at the top of the Park, just beyond the main car parks.
