They sit on a level patch of ground in rolling farmland at Rossnakilla, aligned along a northeast to southwest axis, and between them they span just 7.4 metres. What makes the arrangement worth pausing over is not its scale but its precision. A stone row is exactly what the name suggests, two or more upright stones set in a deliberate linear arrangement, a form found across prehistoric Cork and Kerry in considerable numbers, though their original purpose remains genuinely unresolved. Astronomical alignment, territorial marking, and ritual function have all been proposed; none has been conclusively demonstrated.

The three stones vary noticeably in their proportions. The northeast stone stands 2.05 metres high but is relatively thin, only 0.35 metres through. The middle stone, set 1.85 metres to its southwest, is shorter at 1.65 metres but considerably thicker. The tallest stone of the three occupies the southwest end of the row, rising to 2.1 metres, and is the broadest as well, measuring 1.5 metres in length and 0.65 metres through. Researcher Seán Ó Nualláin catalogued this alignment in 1988 as part of a wider survey of Cork stone rows, placing it within a regional tradition that appears to date to the Bronze Age, roughly the second millennium BC, when such monuments were erected across the upland and lowland landscapes of southwest Ireland.
