The outer face of the bank, on its eastern side, has a lime kiln funnel set directly into it, a detail that speaks to the practical, unsentimental way later generations treated ancient monuments as convenient raw material. A lime kiln was a stone-built structure used to burn limestone and produce quicklime for agriculture and construction, and whoever built this one apparently found the existing earthen bank a perfectly serviceable place to site it.

The earthwork itself is a rath, the Irish term for a roughly circular enclosure defined by a raised bank and an outer ditch, built during the early medieval period as a farmstead or enclosed settlement. This example survives only partially. An arc of about thirty metres runs from north-north-west to south-south-east, formed by an earthen bank rising roughly 1.8 metres above the interior, with a fosse, or outer ditch, about 1.2 metres deep running from north-north-west around to the east. The bank is stone-faced on its inner side, a construction detail that adds some structural solidity to what would otherwise be packed earth. The remainder of the circuit, from south-south-east back around to north-north-west, has left no visible trace above ground, suggesting that portion was levelled or eroded away at some point.

What survives is a partial arc in a field, easy to overlook and carrying no dramatic visual presence. But the combination of a stone-faced early medieval bank, a partially surviving fosse, and a post-medieval lime kiln embedded in the outer face makes this a compact record of how the same patch of ground was used, adapted, and quietly repurposed across a very long stretch of time.
