I can go one better.....found a stone circle mentioned in....
"The Ancient Monuments of Dorset a definitive list" by N.H. Field and J. Bugler
Mayne Stone Circle at West Knighton SY723870
http://www.themodernantiquarian.com/browse.php?site_id=3054
After adding the site to TMA I found that this Dorset (non) circle has no stones, not one bloody stone!...........
Any idea what and when caused the demise of this circle?
