The ogham stone now associated with Bawnaglanna in County Kerry is not actually at Bawnaglanna any longer, and the spot recorded here is simply where it came from, not where it can be found. Ogham is an early Irish script, typically carved as a series of notches and strokes along the edge of a standing stone, and most examples date from roughly the fourth to the seventh centuries. This particular stone had already been broken at its base before modern scholars got to it, and by the time it was formally recorded in 1986 it had been purchased by a landowner and repositioned on the southern bank of a ringfort some distance from its point of origin.

The stone's original location appears to have been in or near a separate circular enclosure, the kind of earthwork that in Ireland usually served as an enclosed farmstead during the early medieval period. A local account published by Lynch in 1908 described the stone as considerably larger than it now appears, the surviving fragment measuring roughly 0.67 metres in height and 0.33 metres across. R. A. S. Macalister, who compiled the definitive early twentieth-century corpus of Irish ogham inscriptions, included this stone as number 248 in his 1945 catalogue, working from Lynch's earlier description. The inscription he read is fragmentary, the damage making certainty impossible, but the partial text runs: QET[IA?]S M[A?]Q TRENIL[U?], which follows the common ogham formula of a personal name followed by MAQI, the Old Irish word for "son of", and a father's name. Who exactly these people were, and what connected them to this corner of Kerry, the broken stone no longer says clearly enough to tell.
