The National Museum of Computing

One of few hands on working museums that offer an exceptional immersive experience. Follow the development of computing: starting with the working Turing-Welchman Bombe and Colossus machines of the 1940s through the large systems and mainframes of the 1950s, 60s and 70s, to the rise of personal 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. We house the full collection of working codebreaking machines and so much more. Currently we are open to the public Tuesday, Thursday, Saturday and Sunday (10:30am - 5pm). TNMOC operates independently of the Bletchley Park Trust, although we are located on the Bletchley Park Estate. To visit us, go through the main Bletchley Park entrance, walk or drive bearing left beyond the main car park, to our separate entrance located at the top of the Park.
