A limekiln was used to burn limestone at high temperatures to produce quicklime, essential for fertilising fields and mortaring buildings. That one was constructed directly into the body of an ancient monument says something about how later generations regarded the landscape they farmed, not always as archaeology, but as convenient raw material.

The ringfort itself, known in Irish as a rath, is a substantial example of the form. Ringforts were typically enclosed farmsteads of the early medieval period, roughly 500 to 1000 AD, defined by one or more earthen banks and ditches that provided both a degree of protection and a clear boundary for a family's dwelling and livestock. This one measures approximately 42.8 metres north to south and 39 metres east to west, its circular interior defined by an earthen bank standing some 2.4 metres high. A fosse, the ditch that runs outside the bank, is present along the northern to southern arc, though it has been partially filled with stones at some point in recent times. There is a gap in the bank to the west-southwest, which likely marks the original entrance. The interior slopes gently from east to west, following the natural contour of the hillside below the ridge crest.

The site sits in pasture, still grazed, which means the earthworks have been maintained by land use rather than by any formal conservation effort. The limekiln remnant to the south-southwest, now collapsed into the bank it once occupied, is easy to miss amid the grass and stonework, but it rewards a closer look as a layering of two very different kinds of agricultural history occupying exactly the same ground.
