Known as ‘Grania’s Bed’ on the original 1834 map and later as ‘Dermot and Grania’s Bed’ on the 1848 edition, this location has all the hallmarks of a lost megalithic site, yet no physical evidence of such a structure exists today. The romantic name references the legendary lovers from Irish mythology; Diarmuid and Gráinne, who supposedly sheltered in dolmens and caves whilst fleeing from Fionn mac Cumhaill. Such names were commonly given to prehistoric monuments across Ireland, particularly portal tombs and other megalithic structures.

What remains at the site today is merely an outcrop of natural rock, bearing no trace of human modification or ancient construction. However, historical records suggest there may once have been more to see here. The 1834 Ordnance Survey Name Book tantalisingly mentions an ‘ancient grave’ at this location, though frustratingly provides no further details about its appearance or condition. By 1903, when surveyors returned to document the area for more detailed mapping, the story had shifted; the later Name Book describes the rock as having been ‘used by the ancient Irish for devotional purposes’, suggesting perhaps a ritual site rather than a burial monument.

Despite its inclusion in multiple surveys of Irish megalithic tombs and its designation in the Sites and Monuments Record, archaeologists have concluded there’s no reliable evidence that a megalithic tomb ever stood at Cratlagh. The site remains an intriguing mystery; a place where folklore, early archaeological assumptions, and the landscape intersect, leaving us to wonder whether the ‘ancient grave’ mentioned in 1834 was already a folk memory of something long vanished, or simply a misidentification of natural rock formations that captured the romantic imagination of early antiquarians.
