Silbury hill - what is it? Appart from the Marlboroigh mound there is also a very large mound in Lewis which people suspect my be similar to Averbury. I gether there may be others - does anyone know anything about this?
On EH's classification system it is one of only 4, all in Wilts or Dorset http://www.eng-h.gov.uk/mpp/mcd/mon.htm
Guess I'd add Dragon Hill to that, although it's smaller and not designed from scratch.
Silbury hill, what is it? Heck, that's a can of worms... I guess at the moment it's a piece of very important cultural heritage in extreme danger.
