The ancient structure, known locally as ‘The Giant’s Grave’, consists of what remains of a substantial stone gallery that once stretched at least 6.2 metres in length, oriented east to west along the ridge.

Today, visitors will find two standing stones, or orthostats, that mark the southern side of what was once a much larger monument. The eastern stone rises 1.3 metres high, whilst its western companion stands slightly shorter at 0.95 metres. These survivors are set within a low, grassy mound that measures 12 metres from east to west, narrowing from 17 metres wide at the western end to 13 metres at the eastern end. Mid-19th century Ordnance Survey documents reveal that the northern side of the gallery had already been dismantled by the 1840s, leaving only these southern sentinels to hint at the monument’s original grandeur.

Whilst archaeologists have been unable to definitively classify this particular tomb type, its substantial construction and prominent positioning suggest it held considerable importance for the Neolithic communities who built it. The site was first sketched in 1834 and has been documented numerous times since, most notably in Eamon Cody’s comprehensive Survey of the Megalithic Tombs of Ireland. A field fence now crosses the western end of the monument, and several loose stones scattered about the area, once thought to be part of the structure, are now considered incidental to the original design.
