First recorded on the Ordnance Survey maps of 1834-5, this enigmatic monument lay close to the road running southwest from Ballindrait, overlooked by Croaghan Hill to the south. The site captured the imagination of early surveyors and antiquarians who documented what appeared to be the remains of an ancient tomb.

When Thomas Fagan visited in 1846, he found what he described as ‘the ruins of a giant’s grave’ oriented almost east to west, measuring roughly 4.7 metres long and varying between 0.9 and 2.15 metres wide. The structure was enclosed by seven great flat stones, some reaching up to 2.4 metres in length and standing between 0.6 and 1.4 metres high. About 1.7 metres to the west lay a substantial slab measuring 1.8 metres long, 1.7 metres broad, and 0.6 metres thick. The original OS surveyors had noted these as ‘a few stones having the appearance of antiquity’, whilst the official Memoir referred to them as ‘some large stones, called a Giant’s Grave’.

By 1904, however, the monument had completely vanished from the landscape. When archaeologists Ruaidhrí de Valera and Seán Ó Nualláin visited in the early 1950s, they could only find low stones embedded in the roadside hedge where the structure once stood, though they couldn’t determine if these were part of the original monument. A single large stone of uncertain origin was spotted in the hedge during a 1984 survey. Whilst Fagan’s detailed account suggests this may have been a megalithic tomb, the lack of surviving evidence means its true nature remains frustratingly uncertain; another piece of Ireland’s prehistoric puzzle lost to time.
