Of course, you could argue that Druids and pagans have no more right pray at Avebury than anyone else - you might be right; difference is that Druids and pagans don't have many places to call their own and Avebury sort of fits the bill. Seems to me that while Druids may not have had anything to do with the construction of Avebury, latter-day Druids and pagans are probably more 'connected' to the place than any other religious/spiritual group. Christians, neo-Nazis, and those who follow the Germanic mythological tradition, certainly have no historical connection to the Avebury Circle but they do have their own churches, parade grounds and places with names derived from the Germanic pantheon - I suggest they go there to worship and leave Avebury well alone.
