The site of a round cairn of late Neolithic or Bronze Age date.  It was opened in 1865 and cup-marked stones were found as well as pottery sherds, a flint knife and the remains of a cremation burial.  Later an urn was found nearby and reburied in the west hedge of the field, 107 metres west of the monument.


On the interior south wall of the cist is a deeply incised phallic symbol, not seen by Megaw 'which has not hitherto been reported and is unique on the Isle of Man'.
