You are right Ken - it IS a beautiful dolmen/portal tomb/whatever, and how anyone can pass by it without a feeling of awe is beyond me.
Is there a rope around it now? How awful. When I visited in 1999 and 2001 you could go right inside it, and I even dowsed a fascinating and unusual (unique!) ritual (for equinox?) movement route there - so I'm glad I had that opportunity then. It WAS terribly over-run with visitors, but shortly after I left the site (in 2001), and got into my car to draw up some plans, I noticed they'd all gone - why? - it was lunchtime!
Something is not right. This message is just to keep things from messing up down the road
