The Trevethy Quoit is a fine example of the Cornish portal tomb dating between 3500 - 2600BC I visited this site during the day just to get a location lock on my sat nav as I planned to return that night. As fate would have it on my way there in the dark my Sat Nav died and I became disoriented. I would love to return and try again because I loved this site. Its quite a large dolmen and it has a really good energy about it. I also wanted to try a few new things under the clear starry skies of Cornwall.
