This intriguing behind-the-scenes tour reveals how the British broke one of the greatest secrets of World War II: the brilliant German Enigma code.
Enigma was the backbone of German military and intelligence communications and was considered unbreakable. The code breakers were sworn to secrecy for decades until the story of Bletchley Park was finally released.
It was in Huts 3, 4, 6 and 8 of Bletchley Park that the highly effective Enigma decrypt teams worked. To speed up the code breaking process, the brilliant mathematician Alan Turing developed an idea originally proposed by Polish cryptanalysts. The result was the Bombe: an electro-mechanical machine that greatly reduced the odds, and thereby the time required, to break the daily-changing Enigma keys. This was arguably the world’s first working computer.
The code breakers were sworn to secrecy for decades until the story of Bletchley Park was finally released.
You'll also have free time to explore some of the other exhibitions, including the fascinating story of Bletchley Park post office and garages with a collection of vehicles from the 1930s.
