Today we celebrate 80 years of Colossus, the code-breaking computer that played a pivotal role in WWII.

Today we have released a series of rare and never-before-seen images of Colossus, in celebration of the 80th anniversary of the code-breaking computer that played a pivotal role in the Second World War effort.

The Colossus computer was created during the Second World War to decipher critical strategic messages between the most senior German Generals in occupied Europe, but its existence was only revealed in the early 2000s after six decades of secrecy.
