The Megalithic structure of Men-an-Tol means 'holes stone'. The site consists of four stones with two upright stones with the holes stone between them. There is a fallen stone at the foot of the western upright. The purpose of the stone remains a mystery. It is sited in open moorland and lies to the east of a track running north-east from Bosullow and can also be reached from Boskednan via the Nine Maidens/Boskednan Stone Circle.
