What makes its absence worth noting is the paper trail it left behind: the Ordnance Survey mappers of 1841 to 1842 recorded it as a rectangular structure and labelled it 'Giant's Grave', the folk name commonly given to megalithic tombs across Ireland, reflecting a widespread tradition of attributing oversized ancient monuments to a race of giants. By the time the revised edition of the map was produced in 1914 to 1915, the name had quietly gained a bracketed qualifier, 'Site of', signalling that even the physical remains had gone.

The site lies in a subdenomination of Ballyline called Grafa, a placename that translates roughly as 'grubbed land', suggesting an area that had been cleared, likely for agriculture, at some point in the past. That history of clearance may itself help explain why the structure did not survive. The Ballyline river runs to the east of the site, flowing north-west through the landscape. Beyond that, the record is spare: no dimensions, no account of what the rectangular structure consisted of, no record of excavation or removal. The 1841 map depiction is the closest thing to a description that survives.
