Men-an-Tol by Star Watcher on Flickr.

Possibly the remains of a Neolithic tomb, Mên-an-Tol is steeped in legend and folklore and has been used for thousands of years as a place of ritual and healing. The stones consist of two uprights with a circular holed stone in their centre and a fourth stone which has fallen. It is highly likely that the stones of Men-an-Tol are the result of a collapsed Dolmen tomb or a stone circle and have been repositioned, possibly more than once during their history.
