You will be part of the community conserving the Historic WW2 Building for all to continue to be educated by engaging with our world class working collection and be  inspired by our history, the innovators and their legacies

The National Museum of Computing, located on Bletchley Park, is an independent charity housing the world's largest collection of functional historic computers and WW2 code breaking machines, including, Enigma, Lorenz, the only working Turing-Welchman Bombe, the rebuilt Colossus, the world’s first electronic computer, and the WITCH, the world's oldest working digital computer. 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 Sandford awarded Learning Programme for schools and colleges from primary school age through to PhD. We introduce computer coding to young people to inspire the next generation of computer scientists and engineers with a special emphasis on supporting female, minority and disadvantaged students. 

We have a proven track record of bridging digital divides  and inspiring future computing professionals.

Why are We Fundraising?

We need to raise £150,000 in matched funding to restore our roof. We are reaching out to ask you to join the community of people who help us continue to conserve British computing history, engage, educate and inspire our visitors and future generations. Our museum is located in Block H on Bletchley Park. Block H, grade two and  listed, dating from WW2, was the world’s first data centre containing Colossus electronic codebreaking machines and now houses our world class collection of working exhibits, including our unique working reconstructed Colossus. 

We have successfully received the bid From The Post Office Remembrance Fellowship  willing to award significant funds to help us restore the roof over the Colossus and adjacent galleries as part of an essential project to improve our visitor experience and facilities. Project details are available.

Why Now? Over the years we have patched and repaired  parts of the roof from limited museum funds, but with the passage of time and a changing climate, the time has come to replace the original structure with a modern waterproof and insulated roof to protect the building and preserve its contents for future generations. 

Problems and risks: roof leak threat to major exhibits, aging plumbing leaks, poor environmental conditions (temp and humidity) threaten collection, renewal and better insulation will address these and help us be more energy sufficient, making museum more sustainable.

How it will work

Step 1. A funding application has been submitted for £500,000  to a charitable trust. Our successful bid needs us to raise a matching £150,000 to meet the total project cost of ~£650,000 

Step 2. We achieve our matched funding target through seeking sponsorships & crowdfunding

Step 3. We deliver the project  (Phase 1) to conserve Tunny & Colossus, and increase the welfare facilities for all of our visitors

Our Mission:

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. We are an accessible museum supporting others to fuel the future.

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

Our 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 our active, Sandford awarded education programmes, festivals, lectures, visitor activities, and interpreted exhibitions and interactivity to raise awareness and inspire future generations of computer scientists, engineers, programmers and inventors.
