The western side of the interior has been built up by as much as 2.3 metres to compensate for the natural fall of the hillslope, a small but telling piece of effort that speaks to how seriously the site's builders took the idea of a flat, usable floor. That raised platform now holds the foundations of a circular hut, roughly ten metres across, sitting at the heart of the enclosure like the memory of a room.

A rath, as ringforts of this earthen type are generally known, is a roughly circular enclosure defined by one or more banks and ditches, and was typically used as a farmstead during the early medieval period, broadly between the fifth and twelfth centuries. This one sits on a north-facing slope near Cúil Aodha in mid Cork, looking out over the Sullane River. The enclosure is nearly circular, measuring 26 metres north to south and 24 metres east to west, with an earthen bank still standing to an internal height of 1.2 metres in places and a shallow external fosse, or ditch, running along its outer edge. Gaps in the bank survive to the north and west, likely the original entrance points, and there is stone-facing visible on the exterior to the northwest, suggesting the builders reinforced at least part of the structure with dressed material rather than earth alone.

The site is now in pasture and partially overgrown with deciduous trees, which give the enclosure a slightly secluded quality. The tree cover makes the bank easier to read in certain lights, particularly when bare branches throw the earthwork into relief, and the hut foundations at the centre remain visible at ground level.
