| I used to work at GCHQ (Government Communications Headquarters) in Cheltenham and had regular visits to a wartime listening station at Great Malvern, where certain arrays were still in use. I know that intercept stations are not what you are after but the cryptanalysis could have been done virtually anywhere. Usually, as Peter says, in large country houses far from prying eyes.
