The National Museum of Computing - Destination Milton Keynes

The National Museum of Computing

The National Museum of Computing, located at Bletchley Park houses the largest collection of functional historic computers in the world, including a rebuilt Colossus, the world's first electronic computer and the WITCH, the world's oldest working digital computer. Visitors can explore seven decades of computing - from the ultra secret pioneering efforts of the 1940s through to the large systems and mainframes of the 1950s, 60s and 70s and the rise of personal computing in the 1980s and beyond.
