A short-horned Neolithic cairn, orientated west-northwest to east-southeast, located 400 metres northwest of Ballafayle house, to the east side of the lane.  It is a Protected Monument.


According to P.M.C. Kermode it is a horned barrow without passage or chamber, containing a cremation burial.  Measuring from tip to tip of the horns it was originally 19 metres, the cairn itself measuring 17.5 metres from the middle point of this chord to the far end.  The remains of the curved facade of the forecourt were visible and 16 metres of the one retaining wall built of coursed slabs and converging towards the southeast end.  The forecourt was paved and the body of the cairn consisted of loose stones.


It now consists of a wall up to 20.0 metres long west-northwest to east-southeast and 0.3 metres high, its top being level with the interior.  This wall begins to curve at its east end.  From the west end of this wall another wall, turf capped and 0.7 metres thick and 0.8 metres high, curves off to the south-southeast.  The tops of some erect stones are exposed here.  Two others have heights of 1.0 and 0.7 metres with average sides of 0.5 by 0.3 metres.  Around the remainder of the site are a considerable number of small prostrate stone slabs.  A well-built wall-face of long slabs revets the northeast side of the cairn for a length of 16 metres.  At the southeast end is a vertical joint, and a wall of smaller stones continues as a facing of the rounded rear of the cairn.  Along the southwest edge, which Kermode did not investigate, a wall-face of small stones can be traced.  In the southeast part of the cairn several upright slabs protrude, but their function is obscure. Kermode suggested that the present rounded end of the cairn was an addition to a square-ended cairn.  Ballafayle belongs to the long barrow or long cairn tradition, without a stone chamber.
