What survives is modest: a curvilinear scarp on one side that still manages a height of about 0.8 metres and a width of nearly 8 metres, and on the other side a barely legible trace, just 15 centimetres high, that requires some patience and the right angle of light to read at all. Improved pasture, generations of ploughing, and a road cutting across the north-east sector have collectively reduced what was once a defined earthwork to something that hovers at the edge of visibility.

Ordnance Survey maps from 1840 and 1904 both record the feature as a sub-oval enclosure, which at least confirms that it was already being documented before it faded further into the landscape. A 1930 study by Flanagan tentatively connected this area with an earthen fort known as Dún na Sciath, a name meaning roughly "fort of the shields" in Irish. The 1904 map places the labelled site of Dunnasgiath about 270 metres to the north-east, which introduces some ambiguity about whether the enclosure and the named fort are truly the same feature or merely neighbours whose histories have blurred together over time. An enclosure of this type would broadly belong to the category of ringfort, a form of enclosed farmstead that was common across Ireland during the early medieval period, typically defined by an earthen bank and ditch encircling a domestic or agricultural space. Whether this particular example ever carried the defensive or ceremonial weight implied by a name invoking shields remains an open question.
