The effect is one of archaeological layering made visible: one era of farming activity slicing through the remains of an earlier one, with neither making much concession to the other.

The site is known as Cahernacullia, or Cathair na Coille, a cashel, which is the Irish term for a stone-walled ringfort, typically a farmstead of the early medieval period enclosed by a dry-stone wall rather than an earthen bank. As recorded by Cuppage in 1986, the enclosing wall survives unevenly. To the east of the later field wall it has been reduced to a low, grass-grown bank, while elsewhere the original outer face can still be traced in large boulders set either upright or laid horizontally, with spreads of collapsed stone visible in places. Inside, on the western side of that intruding field wall, lie the foundations of what appear to be a pair of conjoined circular huts, their eastern extent now hidden beneath the later stonework. The ruined walls of these structures survive to roughly half a metre in height, with the internal dimensions recorded as 2.7 metres for the smaller and approximately 6.52 by 8.9 metres for the larger, suggesting domestic or agricultural use on a modest but practical scale.
