Bletchley park was meant to be a casual day spent seeing a neat house. Instead it was a day learning of the original owners of the mansion, the perceptions and experiences of English people during WW2, and the conservation and preservation efforts needed to reestablish the location. Bletchley itself is puzzle of sorts. There are still unknowns, and they have found treasures even as they believe they have found all that they will. One brief and unassuming train ride from London yields a wealth of information and context that is unavailable anywhere else in the world.
