About Bletchley Park
Bletchley Park is a place of exceptional historical importance, open daily to visitors
Bletchley Park is a vibrant heritage attraction and museum, open daily to visitors.
It was the home of British World War Two codebreaking; a place where technological innovation and human endeavour came together to made groundbreaking achievements that have helped shape the world we live in today.
This unique site was previously a vast Victorian estate, where parts including the Mansion still survive, expanding during wartime to accommodate Codebreakers Huts and Blocks.
During World War Two, the Government Code and Cypher School (GC&CS), now known as the Government Communications Headquarters (GCHQ), was based at Bletchley Park. It grew from a small team of specialists to a vast intelligence factory of thousands of dedicated women and men. This extraordinary combination of brilliant and determined people and cutting-edge technology contributed significantly to Allied victory. In tough conditions, they provided vital intelligence and developed pioneering technological innovation that had a direct and profound influence on the outcome of the war.
The site continues to reveal secrets and tell fascinating stories of our national legacy.
