Well I have another puzzle, four stone, stone circles, why? they obviously make a square.
When Postman put in the photos a four post setting a few days ago, I had just noticed in a book I was reading the four stones at Walton, Powys, you can see photos

4 to 6 feet in height and about 6 feet space in the middle. Looking at the Meini Hirion stone circle and you can almost see a four stones set in a square, is this because they are a guide to building the circle or entrances. I suppose there is no answer to these enigmatic 4 stoners apart from the long and short of it all.....
