As a tourist site, Bletchley Park has been something of a well-kept secret. That's because it was a government secret as well.

But the once-classified home of Britain's World War II code-breakers is finally coming out of the shadows. Though eclipsed by attractions like the British Museum and Stonehenge, the museum at Bletchley Park expects a surge in visitors as a result of The Imitation Game, a movie about Alan Turing, a computer science pioneer and architect of the effort to crack Nazi Germany's Enigma cipher.

The film starring Benedict Cumberbatch was nominated for eight Academy Awards.
