Fascinating Galleries

Museum in Block B

The galleries in Block B house a range of displays and exhibitions that all tell part of the history of Bletchley Park, including our Enigma collection and a brand new Alan Turing £50 note gifted from The Bank of England. We are looking forward to welcoming you and sharing our story with you.

The Life and Works of

Alan Turing display

Alan Turing is one of the most well-known Codebreakers to have worked at Bletchley Park, helped by the 2014 Oscar winning film, The Imitation Game. For the early part of the war, he was Head of Hut 8, working on decrypting German Naval Enigma messages. In this display, discover more about his genius at Bletchley Park, his later work on computing, and his ongoing legacy today.

Breaking of

the Lorenz cipher

Perhaps Bletchley Park’s greatest success was breaking the German’s strategic cipher, Lorenz. This complex cipher was used to secure communications between Berlin and German Commanders in the field. Featuring rare Lorenz messages, this display tells the story of how the Codebreakers broke Hitler’s “unbreakable” cipher machine.
