In the level pasture of Kiltanna in County Limerick, one such enclosure sits conjoined on its northern side to a second, very similar structure, the outer edge of the southern fort lying just four metres south of the outer edge of its neighbour's fosse. Whether this pairing reflects two households, a farmstead with a separate enclosure for livestock, or some other arrangement lost to time is not recorded, but the proximity alone marks this out from the thousands of solitary raths scattered across the Irish countryside.

A rath, or ringfort, is an enclosed farmstead of early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries, and built by encircling a circular area of ground with an earthen bank and an outer ditch called a fosse. Here, the enclosure has a diameter of twenty-nine metres. The bank still stands to an internal height of about a third of a metre and rises to nearly one and a half metres on its outer face, suggesting the exterior was deliberately heightened to present a more imposing boundary to the world outside. A level berm, a flat shelf of ground four metres wide, separates the bank from the fosse, which is recorded as being around seventy centimetres deep and eighty centimetres wide, though much of it has been infilled with dumped material over the years. The record was compiled by Denis Power and uploaded to the national archaeological inventory in August 2011.

The site sits in ordinary farming land, and the interior of the southern enclosure is largely under pasture, making the form reasonably legible if you know what you are looking at. The western half, however, is covered in dense overgrowth, which can obscure the bank line and make the boundary harder to follow on that side. The northern companion enclosure adjoins directly, so it is worth walking the full perimeter to appreciate the relationship between the two. As with most raths in agricultural use, access depends on land ownership, and the usual courtesies of the Irish countryside apply. The earthworks are subtle rather than dramatic, and patience with the vegetation on the western arc will reward a clearer sense of the original circuit.
