Why is Google in love with Bletchley Park?

Technology giant Google normally has its eyes fixed firmly on the future. But it has turned its attention to an old house in England to help preserve a slice of computing history.

For nearly half a century after World War II, a Victorian manor house in Buckinghamshire lay neglected and unloved, its dilapidated buildings falling into disrepair.

By the early 90s, plans even emerged to tear down the assorted boarded-up huts around the house and erect a supermarket in their place.

For reasons of national security, a veil of secrecy shrouded Bletchley Park. Only in the last 20 years has the extraordinary story of breaking the code of the German Enigma machine finally become well-known.
