This is what survives of a possible rath, the Irish term for a ringfort, one of the most common monument types in the Irish landscape. Ringforts were typically circular enclosures bounded by earthen banks and ditches, used as farmsteads and settlement sites during the early medieval period. Most are found in open farmland; this one ended up absorbed into suburban development on the eastern outskirts of Killarney.

The 1846 Ordnance Survey six-inch map records the feature as a circular enclosure roughly twenty metres in diameter, its perimeter planted with trees, which was a common way of marking or preserving such features on agricultural land in the nineteenth century. What remains today is considerably less legible. A north-south earthen bank runs for approximately fifty-six metres, with a width of around five metres and a height of just under a metre. Large stones have been placed against it at some point, and these may incorporate original structural elements of the rath, though it is difficult to say with certainty. The slight curve at the southern end is the most suggestive detail, a faint echo of the circular form recorded nearly two centuries ago.
