The National Museum of Computing

The Colossus Gallery

World-famous rebuild of the first electronic computer. Colossus, the world's first electronic computer, had a single purpose: to help decipher the Lorenz-encrypted (Tunny) messages between Hitler and his generals during World War II. The Colossus Gallery housing the rebuild of Colossus tells that remarkable story.

 

The Tunny Gallery

From intercept to decrypt during World War II. The Tunny Gallery, along with the Colossus Gallery, shows the entire World War II code-breaking process of the Lorenz-encrypted messages (Tunny) from signal intercept at the Knockholt receiving station in Kent to the production of the final decrypts on Tunny machines in Bletchley Park.
