It carries an ogham inscription, the early medieval Irish writing system that uses a series of notches and strokes cut along a central stemline, but the markings are so heavily weathered that no one has yet been able to read what it says. That is not unusual for ogham stones in general, but there is something particularly suggestive about this one: it was not found at a ringfort, a burial site, or a monastic enclosure, but washed up on Fermoyle beach, near Cloghane on the Dingle peninsula.

The stone itself is of old red sandstone, a rock type common to the region, and runs to 1.65 metres in length with a maximum width of 0.4 metres and a thickness of 0.25 metres. Its long, linear shape is typical of the standing stones on which ogham inscriptions were most often carved, usually to commemorate a named individual and their lineage. How it came to rest on a beach is unknown. It may have been moved, fallen, or simply deposited somewhere along the coast over time, gradually worked by the elements until whatever message it once carried became illegible. It is now catalogued in the Kerry County Museum collection and a full scholarly description was, at the time the stone was recorded, being prepared for publication.
