Irresppective of whether Stonehenge was a case in point, and with reference to the comment below about hearing the sound of drumming coming from WKLB, the hypothesis that our forebears created, on occasion, places with a deliberate auditory element to them, or utilised caves and other geological features with that facility remains valid. They were very probably greater sensualists than we are, to our detriment, appreciating what the natural world had to offer, be it sound or visual, for example auroras or the sun and moons reflections in water filled cup or bullaun stones. We should recognise, appreciate and respect that, and not deride.
