An immersive cinematic experience exploring Bletchley Park’s secret D-Day role.
Discover the vital importance of the Ultra intelligence produced at Bletchley Park, and the impact it had on one of the most important military operations of the twentieth century.
Featuring a specially commissioned film projected on a 22m screen, the audio-visual experience is located in the restored Teleprinter Building where hundreds of thousands of intercepted messages first arrived at Bletchley Park from secret listening posts across the UK, and Ultra intelligence was transmitted to Allied headquarters.
