About The National Museum of Computing
Explore the world's largest collection of working historic computers at The National Museum of Computing (TNMOC), located on the historic Bletchley Park estate in Milton Keynes. Home to the working Colossus - the world's first electronic digital computer - and the WITCH (Harwell Dekatron), the world's oldest working digital computer, TNMOC is the only place on earth where you can see both machines in action. Recognised as one of England's top 100 irreplaceable places, it's a genuinely unmissable day out for curious families, STEM fans, and anyone who wants to understand how the digital world we live in was built.
Museum highlights:
- Colossus - see a working rebuild of the world's first electronic digital computer, used to break German ciphers during World War II and kept secret for decades after the war ended
- WITCH (Harwell Dekatron) - meet the world's oldest working digital computer, built in 1951 and restored to full working order by TNMOC volunteers
- The Turing-Welchman Bombe - watch this remarkable machine in action and learn how it helped Allied forces decrypt Enigma messages, shortening the war
- Hands-on retro computing - program a BBC Micro, play on original 1980s games consoles, and explore the machines that defined a generation
- Interactive Digital Trails - specially designed challenges for kids that turn the museum into an adventure, from codebreaking puzzles to computing history quests
- Expert volunteer guides - knowledgeable and passionate volunteers who tailor their explanations for every age group, from curious 7-year-olds to seasoned tech professionalsWhy The National Museum of Computing is Worth the TripUnlike most museums, TNMOC puts history in your hands. Visitors don't just look at machines behind glass - they touch them, program them, and play on them. From booting up a vintage BBC Micro to trying your hand at an Enigma-encrypted puzzle, the emphasis is always on doing rather than just watching.The museum traces seven decades of computing history - from the ultra-secret wartime machines of the 1940s, through the giant mainframes of the 1950s-70s, the home computing revolution of the 1980s, and all the way to the present day. It's a genuinely coherent story, and the volunteer guides are brilliant at connecting the dots between the machines on display and the technology families use every day.For families with children who have sensory sensitivities or neurodiverse needs, TNMOC runs dedicated Relaxed opening days - quieter, lower-stimulus sessions designed to make the museum accessible for everyone. Check the What's On calendar for dates.The museum shop is worth a browse before you leave - it stocks T-shirts, books, mugs, build-your-own kits, framed prints, and a range of gifts, with proceeds going directly towards new displays and conservation work.
