Most raths, the common term for an earthen ringfort used as a defended farmstead during the early medieval period, present themselves as more or less complete enclosures. This one is only semi-circular. A later fieldbank, running south-east to north-west, has sliced through the north-east bank, leaving roughly half the original circuit standing. The surviving bank is still substantial, averaging 4.8 metres wide and rising 1.8 metres on its outer face, though it stands only a metre above the raised interior. That elevated interior is itself a telling detail: the ground within sits higher than the surrounding land, the accumulated result of centuries of occupation and use.

What survives inside adds further texture to the picture. Towards the western sector of the enclosure, an oblong mound of stone measuring roughly 4.4 by 7.2 metres, and only about 0.4 metres high, may represent the footprint of a house, the collapsed remains of a structure that once stood within the protected space of the rath. Alongside this possible house-site, two low ridges run north to south across the interior, a pattern consistent with cultivation, most likely for growing vegetables at some point in the fort's long post-medieval afterlife. It is a reminder that ringforts were rarely simply abandoned; they were repurposed, built over, farmed, and gradually absorbed into the working landscape around them. The detail is drawn from C. Toal's North Kerry Archaeological Survey, published in 1995, which catalogued the density of such monuments across a county that contains an extraordinary number of them.

The site's internal diameter is recorded at 27.4 metres east to west, which puts it within the typical range for a single-banked rath of its type. The word "univallate" simply means enclosed by one bank rather than the multiple concentric rings that sometimes indicate higher-status sites. Dromnacarra's rath is, by that measure, an ordinary one, a farmstead rather than a chieftain's seat, and all the more legible for it.
