The National Museum of Computing

The National Museum of Computing (TNMoC) is housed at Bletchley Park

It is a separate trust with their own admission fee. The Colossus and Tunny rebuild galleries are open 10.30 – 17.00 (Last admission 16.30) all year round. The rest of TNMoC, which traces the development of computing from Colossus, the world’s first electronic computer, through to the modern-day, has limited opening hours so please check before travelling.

The use of machines to break into Lorenz, the high-grade cipher machine used by Hitler and his High Command to encipher strategic messages was the brain-child of Bletchley Park Codebreaker, Max Newman. Colossus was developed by General Post Office engineer, Tommy Flowers, to help speed up the process.

A rebuild of a wartime Colossus computer can be seen daily by visitors to Bletchley Park at The National Museum of Computing. TNMoC operates independently of the Bletchley Park Trust.
