This one at Clogh sits on that gentle rise with open sightlines in every direction, its oval footprint stretching roughly 48 metres from northwest to southeast and 39 metres across the other axis. A ringfort, in general terms, is a roughly circular enclosure defined by earthen banks and ditches, used throughout early medieval Ireland as a farmstead or defended settlement. At Clogh, what remains is a scarp, the eroded outer face of the original bank, still standing between 1.2 and 1.6 metres high in places, with traces of the encircling fosse, a defensive ditch, surviving along the northern arc of the monument.

When the site was described in 1976, it presented as a large circular ringfort with a low bank, a shallow intervening fosse, and an outer bank beyond that. Even then, the outer bank and fosse were only clearly visible on the northern side. Since that time, the fosse has been infilled around most of its circuit, though its outline can still be read in the ground. The outer bank has disappeared entirely from the surface. Inside the enclosure, two possible house sites were identified in the northwest and southwest quadrants, the kind of internal features that suggest this was a place of habitation rather than purely defensive use. Traces of wall footings, roughly 1.8 metres thick and surviving to about 0.2 metres in height, are visible toward the northwest. The original entrance to the fort has not been identified.
