Hi YP,

Yep, I saw the article too.

St. Eval is in my local area, so I had been aware of the stones.
After I read the piece I went up to have another look.

I have posted pictures of 2 of the stones at...

The theory of a stone circle was first put forward by the historian Baring-Gould in about 1913

There are many prehistoric sites in the area including Trevisker Round which gives its name to 'Trevisker type' urns made by the Beaker folks.

Many Cornish churches were built on pagan sites, alot of them still have circular graveyards.

Another local site is St. Dennis churchyard built on a hillfort. I was lucky to find that my Uncle taken some aerial pics of St. Dennis church/hillfort some time ago. I only scanned them this week if you want to have a look at the hillfort with a church ....
