Those shallow, circular depressions, ground into the stone by human hands perhaps four or five thousand years ago, have no definitive explanation. They appear on megalithic monuments across Ireland and Britain, and scholars have variously interpreted them as territorial markers, ritual symbols, or astronomical records. At Céim Chorrbhuaile, six occur on one roofstone and five on the other, a quiet detail that rewards anyone who pauses long enough to look upward.

The structure is a wedge tomb, a type of megalithic monument built predominantly in the later Neolithic and early Bronze Age, typically characterised by a gallery that narrows and lowers from one end to the other. This example follows that form precisely. The gallery runs roughly east-south-east to west-north-west and measures 3.8 metres in length, tapering from about 1.2 metres wide at the western entrance down to just 0.35 metres at the eastern end. Four sidestones define the north and south walls, a backstone closes the narrow eastern end, and the whole construction is enclosed within a closely set outer walling. The two roofstones overlap each other to cover the gallery, and the height diminishes steadily from west to east, giving the interior a pronounced sense of compression as it retreats into the hillside. There is no surviving trace of a surrounding mound, though that absence is not unusual; many such mounds have simply eroded away over millennia. Recorded and documented by Ruaidhrí de Valera and Seán Ó Nualláin in their 1982 survey of megalithic tombs across Cork, Kerry, Limerick, and Tipperary, this is considered a well-preserved example of its type.

What makes the location quietly remarkable is the proximity of a second wedge tomb, identified at a distance of just 150 metres to the south-south-east. Paired or clustered megalithic monuments do occur in Ireland, and their grouping at Céim Chorrbhuaile suggests this particular stretch of valley may have held some significance for the communities who shaped it.
