[visited 2/10/11] This is an oddity, standing alone outside the neolithic enclosure, nowadays located in a small clearing in the woods. I spent a while here studying this gorgeous stone, enjoying the lovely hot October day.
Its lean is interesting given the theories about it being a crude sundial, certainly it seems deliberate. Though excavation would be needed to be sure. If true it gives a new perspective to other leaning stones in the UK.
Access is fairly easy after a mile or so along footpath to get to the top of the edge. In summer the way is hampered in the wood by all the bracken.
