The largest of them measures 2.2 metres at its widest point and may be set on edge; the other two lie prostrate. They were catalogued under the heading of megalithic tomb, yet the archaeologists who examined them were candid: it is doubtful that they ever formed part of one.

The uncertainty surrounding these stones goes back at least as far as Ordnance Survey fieldwork in 1938. A Field Memorandum from that year recorded the stones as standing on a lios, which is an Irish term for a ringfort or circular enclosure, typically a raised earthen platform enclosed by a bank and ditch. A separate OS Name Book compiled in the same year took a different view, describing the site as a tumulus, a burial mound. Neither interpretation has been confirmed on the ground, because the vegetation is too dense to allow any clear reading of the underlying earthwork, if one exists at all. The stones may be the remains of a prehistoric structure, or they may be something altogether more ambiguous, relocated or disturbed at some unknown point in the past.
