Visiting Bletchley Park

Having enjoyed the book and the film I recently had a chance to visit Bletchley Park and got to visit Alan Turings Office. I’m not sure how realistic it is. I was expecting to see more in the way of blackboards for brainstorming ideas, but maybe he didn’t work like that.

You can imagine the atmosphere that there would have been here during World War 2. The sign on the wall says, Don’t Help the Enemy careless talk may give away vital secrets.

The main house at Bletchley Park

During the war, to the outside world, Bletchley was just a country house estate. The huts in which the codebreakers worked were little more than sheds. You can see from the pictures that it was sunny on the April day when I visited. Even then the huts were hot inside, and that was with a handful of people in them. They must have been unbearably hot in summer and freezing cold in winter.

If you get a chance I highly recommend visiting Bletchley Park and the adjacent National Computing Museum.
