139. This ancient burial monument sits in pasture land broken by rock outcrops, where three field walls converge from the east, south and west. It’s one of three portal tombs found along this side of the valley, positioned just 100 metres from its nearest neighbour and about a kilometre from the westernmost tomb in the group.

The monument’s current state tells a story of considerable destruction over the centuries. Only one original stone remains standing; a portal stone that once marked the entrance to the burial chamber. This impressive orthostat would reach at least 2.5 metres in height if fully upright, though it now leans slightly eastward. Its distinctive shape starts rectangular at the base before tapering to a point about two thirds of the way up. Against this lone survivor rests a massive displaced roofstone measuring 4.2 by 2.7 metres and up to 0.7 metres thick, beneath which lie three other fallen stones partially obscured by heaped rubble. Archaeological evidence suggests this was once an east southeast facing chamber, with the surviving portal stone forming the north side of the entrance.

Historical accounts provide tantalising glimpses of what has been lost. When antiquarian Thomas Fagan visited in 1847, he noted that shortly before his arrival, several large stones had been broken and removed, including a nine foot tall pillar that once stood beside the surviving portal stone. He also recorded ruins of a stone walled enclosure measuring roughly 14 by 12 metres to the southeast, which he thought might have been another burial site but which has since vanished. Later visitor Norman Moore claimed to have seen additional cromlechs and burial mounds in the vicinity in 1872, though these too have disappeared or may have been misidentified features. Archaeological testing in 2004 found no additional remains in the immediate area, though the site continues to be protected as part of Ireland’s ancient heritage.
