Bletchley Park

During the Second World War, Bletchley Park was home to the Government Code and Cypher School – the precursor to GCHQ.

The Mansion at Bletchley Park

The Mansion at Bletchley Park

Today, the site at Bletchley Park explores the story of the men and women who worked here decoding thousands of enemy messages during the Second World War. Under penalty of death, the codebreakers could not divulge what they did nor how they did it – but their efforts helped shorten the war by almost two years.

Exhibits and audio-visuals offer insight into the secret intelligence gathering conducted by the likes of Alan Turing, Tommy Flowers, Max Newman, Mavis Batey and Dilly Knox. Visitors can marvel at the rare 'Abwehr G312', a captured German machine used to encode messages, as well as artefacts, documents and first-hand accounts which reveal tales of spies and strategic deception.

Have a look inside the ornate Victorian mansion that was headquarters to intelligence staff during the War, or simply wander by the lake, relax and observe the wildlife. An exhibit on the film, The Imitation Game, is on view for most of 2015.

Permanent collections

Bletchley Park's Art Fund Prize-nominated exhibition, The Life and Works of Alan Turing, presents important papers belonging to the genius cryptographer credited as one of Britain's pioneers in computing science.
