The National Museum of Computing (TNMOC) is 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

The National Museum of Computing is open Tuesday to Sunday (and spring/summer bank holidays) from 10.30 – 17.00.

TNMOC operates independently of Bletchley Park Trust, although we are located on the Bletchley Park Estate
