It is not the only ogham stone on the site, which makes the casual domestication of this particular one all the more arresting. Ogham is an early medieval alphabet, typically carved as a series of notched lines along the edge of a stone, used mainly between the fourth and seventh centuries to record names and memorial dedications in an archaic form of Irish.

The enclosure itself is a rath, the most common type of Irish ringfort, built from earthen banks rather than stone. This one sits just below the crest of a hill, its circular raised interior measuring 29 metres in diameter, saucer-shaped and enclosed by a bank that stands 1.3 metres above the interior and 3.6 metres above the outer ground level. Beyond the bank runs a fosse, a defensive ditch roughly a metre deep, crossed at the north-east entrance by a causeway four metres wide. Field clearance stones have been dumped into the fosse on the southern side over the years, a common fate for ancient earthworks in working farmland. More remarkable is what lies in the north-west quadrant of the interior: a souterrain, an underground stone-lined passage of the kind often associated with early medieval settlement, and associated with no fewer than six ogham stones. The combination of a souterrain and multiple inscribed stones within a single rath is unusual and points to a site of some significance, though the precise nature of that significance remains an open question.

The upright ogham stone just north of the causeway entrance, now embedded in concrete and serving as a gate pillar, measures 1.4 metres in height. Old field boundaries run around the enclosure to the west, north, and east, sitting about five metres outside the fosse, suggesting the landscape has been organised around this feature for a very long time.
