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.
