TNMoC
Home to the world's largest collection of working historic computers.
Follow the development of computing: from the Turing-Welchman Bombe and Colossus of the 1940s through the large systems and mainframes of the 1950s, 60s and 70s, to the rise of personal computing and the rise of mobile computing and the internet.
Recognised as one of England’s top 100 ‘irreplaceable places’, we welcome corporate and group visits, schools and individuals from all over the world.
The National Museum of Computing (TNMOC) is located on the Bletchley Park Estate but is independent of the Bletchley Park Trust.
