The National Museum of Computing on Bletchley Park estate

The National Museum of Computing, located on Bletchley Park, is an independent charity housing the world's largest collection of functional historic computers, including 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 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.

Britain has a pioneering computing history. Take a journey through the technologies and discover the people behind them at The National Museum of Computing.

We invite you to experience the 20th century revolution in personal and business computing that transformed lives then – and laid the foundations of digital Britain.

The National Museum of Computing is proud to hold the world’s largest collection of working historic computers. Visit us today and you will meet some of the last century’s most significant technological inventions: 


Experience working rebuilds of famous electromechanical codebreaking machines - including the iconic Bombe from Alan Turing’s team - that broke the enemy’s communications during World War II.

Kick back to the 1980s with our collection of working BBC Micros and other iconic retro systems – while testing your skills on some of the era’s killer games.

Be wowed by the WITCH - the world's oldest working digital computer used to help build Britain’s first nuclear power stations

See the Elliott 803 that belonged to Dina St. Johnston who founded Britain’s first independent software company 

Take our punched-card test with Virtual Flossie – a 3D, interactive re-creation of one of Britain’s first commercially successful computers.


Crucially, TNMOC is a working museum. We not only tell the story of Britain’s world-class technology history and how it affects our lives today, we offer rarely-available hands-on experiences with some incredible machines. 

Pop along to discover if your first computer – or that of your mum, dad, uncle, aunty or grandparents - is in our museum as part of that story!
