Feel a bit of a T*** really......I did a search on sites near to the Bosporthennis Quoit and this didnt' come up....

Bit of a rush at the moment but the photo in the book looks like the same place..and they do describe it in the text as a beehive hut.

Will give it a good study later today, the sun is shining and I have to be up on Bodmin Moor to do a walk.

Thanks for the info all of you
