Of all the enigmatic ancient remains of West Cornwall, none is more puzzling than the Men-an-Tol (stone of the hole). Nobody really knows the purpose of the structure, or even quite how old it is, although most agree that it dates from the early Bronze Age, around 2000 BC. The Men an Tol is actually four stones – one of which has fallen, but three of which remain standing. The hole in the centre stone is just wide enough for an adult to pass through, and traditionally it has been used to promote well-being. It was said that tubercular children could be cured by being passed through the hole three times, and even today many visitors to this ancient site squeeze through the Men an Tol in the hope of good luck and good health.
