"This theory of a "healing centre" strikes me as modern New Age nonsense. In the days of the Trojan War (1200 B.C.?), Homer describes the burning of Patrocles' body on a giant funeral pyre that was a hundred feet each way."
My thoughts exactly. But if it really was a place of cremation, shouldn't there be evidence of a funeral pyre somewhere abouts?
It may sound weird but i always thought the henge was some sort of wind controlling device if it was used for pyres this would make sense to control the side and updraft of the wind in a pyre to completely burn the remains of hero's and villains alike !
Just a random thought ....
