On the outside, the enclosing bank follows the same gentle curve as the rest of the circuit. Step inside, however, and the wall built along the inner face of that same bank runs in a straight line, quietly contradicting the geometry that surrounds it. It is the kind of detail that passes unnoticed at a glance but rewards anyone who takes the time to walk the perimeter.

The site sits on a west-facing slope at Doire Uí Ríordáin Theas, a roughly circular enclosure measuring approximately 19 metres north to south and 18.3 metres east to west. A grass-covered earth and stone bank, rising to about a metre in height and topped by a stone wall, defines the boundary. Ringforts, known in Irish as raths when formed primarily of earthen banks, were the standard farmstead enclosure of early medieval Ireland, typically dating from roughly the sixth to the twelfth century, and several thousand survive across the country in varying states of preservation. This one carries additional layers of later activity: the western half of the interior retains the faint corrugated texture of cultivation ridges, narrow parallel mounds left by spade or plough tillage at some point after the fort's original use had lapsed. A stand of conifers has been planted inside as well, which complicates any reading of the interior but also, in a practical sense, has probably helped preserve it within what is otherwise open pasture.
