Ooh if I was a prehistoric Aveburyite, think how inspired I would have been, digging those ditches up at Windmill Hill, putting up Silbury hill, all in preparation for that special moment when the sun set pointing to a burial chamber hundreds of miles away on another island, in the special moment of 2758 BCE. And weren't the stones raised after this date? Oh well I would have been really impressed anyway.
oh no actually I wouldn't have been. Call me a cynic and that.
