This is my local circle and have visited it semi-regularly since my mid-teens.
I stopped visiting for a period of maybe 7 or eight years returning to the site for the first time about 4 years ago.
I was dismayed to find that the site had deteriated so much in that time. Stones that I recall as fully or semi visible are now dispoiled, broken and/ or hidden.
There was never a great deal to see, even in the late 60’s, early 70’s when I first visited but at least you could easily discern the location of the circle – the triangulation point was always a good pointer, especially when coming straight up the West side of the hill.
