There is a very good site that forms part of the Stone Circle Webring – can’t remember URL or name! – which gives good detailed information about this site. What you see is a lovely little henge, a big barrow and a tiny church. Visited it by accident when at Bournemouth Uni a few years back. The site on the Web-ring reveals a much larger ritual area that points to a very complex and important site in antiquity. Well worth a visit, I found it most relaxing.
