thats an interesting article. He puts forward Maes knoll as the sighting hill from Stanton Drew, it has a later hillfort and the wansdyke running over it as well... but, what about the earlier timber concentric circles that have been found at Stanton Drew - how does that fit into the picture? were the later stone circles put their because there had been a site of significant religious purpose there in the first place, i.e. by the river or because there was a prominent hill about a mile away..
