This site is no longer marked on the OS Landranger map. I reached it by scrambling over the barbed wired hedge running beside the A4260.
When I found it, I was a little confused....it looks like a cairn at the end of a ploughed-out long barrow. Most of the stones don`t look as if they`ve been lying there for thousands of years.
Back home, I did a little research. It seems that in 1843ad a tenant farmer broke up the Hoar Stone. When the landowner found out, he stopped him from doing any further damage.
