The farmer used to come and speak to us when we gathered for the solstice some years ago. He said that on the summits of all the surrounding hills, a King was buried, and that the circle was at the centre, so to speak, of all these. It's pretty high country up there, and i guess the people have always seen themselves as differentiated from those below? Although there'e no exact lay line, as such, a line drawn north from Stonehenge/Avebury, to the Rollright Stones, and then up to Arbor Low, doesn't deviate all that much from a straight line, and i conjecture that these sites were multi purpose, incorporating elements of religion, science, time/space orientation, agriculture, entertainment, and trade.
