I've only visited two of them.
How about you?
Stonehenge, Avebury, Canterbury, Walsingham and a few of the great cathedrals. York , Durham.etc
I couldn't believe it when we found a Stone circle in Kent. It was in a Letts Motor Tour guide. Its an ancient burial mound in Trottiscliffe -
apparently pronounced "Trotsley", the mind boggles.
We took a friend of ours that's into mystical stuff and she took along some divining rods. I tried them out and was amazed by how they span around!
I can categorically deny having visited any one of them!
I have been to Castlerigg though, it's stunning. For a little while you can imagine you are in any year since it was built, give or take a few sheep and cottages in the distance!
Chumley is easier to pronounce, though.
