Ogham is an early medieval script in which letters are represented by groups of notches and strokes cut along the edge of a stone, most commonly used for personal names in commemorative or boundary contexts. This particular stone, a low, roughly rectangular pillar of granitic rock measuring just over a metre in length, carries its inscription along one angle of its long axis, running from the northern end down to roughly the midpoint. The characters are cut on what is now the upper west-facing angle, still legible despite a surface patchy with lichens and moss, the growth thicker on the western face where the stone is most exposed.

Reading the inscription is not straightforward. According to research by Moore in 2001, the text has been interpreted as DOTAGNI, though COTAGNI is also possible. The uncertainty arises from a spall, a fragment of stone that has broken or flaked away at the start of the inscription, which may have taken a couple of scores with it. Those missing notches are enough to change the first letter entirely, and with it the personal name the stone was almost certainly intended to record. Ogham inscriptions in Ireland typically commemorate an individual, often in the genitive case, meaning the stone effectively reads as belonging to or in memory of that named person. Whether the name here was Dotagn or Cotagn, the individual behind it is otherwise unknown.

The stone is prostrate now, lying along the ground rather than upright as it may once have stood, which is not unusual for ogham stones that have survived into the present inside or adjacent to later Christian burial grounds. Visitors to the graveyard can view the inscription along the upper west angle, though the lichen cover means close inspection in good light is helpful for picking out the individual scores.
