When foundations were being dug for the building that now stands at Áth An Charbaill, workers uncovered a cluster of small stone-lined graves, the kind of carefully constructed cist burials common to early medieval Irish sites, where flat stones are arranged to form a rough box around the body. The house was built anyway, and the graves are gone from view, though not entirely from the record.

Before construction began, the Ordnance Survey maps had already marked something here, labelling the spot simply as a 'Grave'. What they recorded, drawing also on observations published by Orpen in 1908, were two upright stones, each around three feet high and set roughly ten to twelve feet apart. Whether these were the remnants of a portal structure, a field marker, or something else is not clear. What the foundations revealed suggested a much wider burial ground than those two stones implied. Further graves have also been recorded approximately a hundred metres to the west, pointing to a site of some extent, now overlaid by the ordinary business of rural life.
