I was not quite sure whether to put this subject on TMA but on reflection as everyone is interested in the old stones perhaps a 'serious' interest in what happens to the bones that have come from these barrows and circles and now reside in museums and archaeological storehouses is a topical subject.
Reburial of bones is attracting a wide range of opinions on the subject, and there is a public consultation going on at English Heritage at the moment.
One essay that seems to cover the matter in a moderate manner has been written by Yvonne Aburrow , an excellent overview of a difficult subject. "Finding a Compromise - Keeping Places"

I know 'sacred space' and 'pagans' do excite some uncalled for comments on the subject, but the main argument here is respect for the dead and what should the archaeologists be doing with the bones they have accumulated over the years - there are many sides to the question of reburial of bones - modern religious or ritual elements need'nt be dwelt upon in a secular argument ;)
