also a marvel, but only a few hundred years old, the whispering galleries, where you can stand in a particular spot and whisper, and someone many feet away can hear it clearly bounced off and across elliptical ceiling and back down. St Pauls Cathedral in London has one, so does US Capitol. Very eerie when you hear it so clearly, but still the volume of a whisper...
