Men-an-Tol standing stones

Possibly one of the best known and least understood monuments in Cornwall, it probably dates from the late Neolithic or Bronze age (2500-1000 BCE). At least one of the stones is thought to have been moved in Georgian times. The function of the stones is not known but suggestions have included an astronomical observatory, fragments of a stone circle, or part of a burial mound. Local tradition has it that rickets can be cured by passing the afflicted child through the holed stone.
