Whatever it became , fanciful reconstruction , corral etc. who knows .What we do know is that it had a cinerary urn ,dated from the Middle Bronze Age ,containing cremated bone , buried in a pit and covered by a cairn , alongside were were two flint scrapers and a flint knife . Another pit containing a cremation was close to the pit and near the centre was a cist with a cup marked capston .A third pit was filled with stones and had another cup marked rock close to it. Nine stones , possibly not socketed but merely held in place by an embanked ring encircled the pits/cairn .The tallest stone was in the SW . All that adds to me as a ritual site unless of course all this cremated bone and marking rocks stuff was really an early form of Steinerian biodynamics and it was really a walled garden.
