Britain's best kept secret

Ever heard of Enigma, Bombe or Colossus ? What about Bletchley Park ?
Well, during WWII, British codebreakers arrived in August 1939 in Bletchley Park in order to crack the German Enigma cipher. You can see the mansion in the park below:

Thanks to the works of Polish cryptanalysts, the mathematician Alan Turing could develop an electro-mechanical machine called Bombe that reduced the time required to crack the daily-changing German code.



The scientists were working in huts like this one to decrypt German intercepted messages. A forerunner of today's computer was also invented: the Colossus who could read paper tape at 5000 characters per second for example.



The wartime information about Bletchley Park was declassified in the mid 70s only and even now, not everything is known about it.
