"Implied direct link with modern Pagans..." ???

I'd have thought they have less reason to claim a connection with Stonehenge than almost anywhere else you could think of ... Unique construction, no precursors, no predecessors... so it might have been built by anyone, from anywhere, quite likely people who slaughtered the locals and destroyed their culture.

Also, where could they put this cemetery? Not in the zone of the dead, as it's pure archaeology. But not in the the zone of the living either, since wouldn't that be a blasphemy against the beliefs of the original people? They'll have to go well away, Salisbury perhaps, and create a zone of the Pagan Undead...
