Well this is a bit strange:
"It tells us a lot about why Stonehenge was located where it is and why they [prehistoric people] were so interested in the solstices. It's not to do with worshipping the sun, some kind of calendar or astronomical observatory; it's about how this place was special to prehistoric people."
I'd have thought it pointed to all those things. And as for being interested in the solstices not being to do with worshipping the sun how does he work that out?
