Came across an interesting article in WAM 1998 article last week. P.Ashbee - Stonehenge - Its possible non-completion, slighting, and dilapidation...
In it he argues that Stonehenge like Avebury were places that were reused by the romans for worship, a cult might have existed. Romano - british interest is found in both the above monuments, plus longbarrows (WKLB), Newgrange and Tara, as also the siting of temples on henges point to continuation?? of acknowledgment of old shrines.
The vanished stones (or not being there in the first place) of Stonehenge bit was also interesting, but people have to read the article, did'nt mention the Berwick stones...
