A cashel is a dry-stone ringfort, typically a circular or roughly circular enclosure built of unmortared stone, common across Ireland during the early medieval period and sometimes earlier. What makes this particular remnant quietly interesting is its shape: not the rounded or rectangular form one might expect, but a trapezoid, wider at its eastern end than its western, stretching roughly 12.8 metres from east to west and narrowing from about 6.3 metres to 4.6 metres across.

The walls themselves have largely disappeared into the earth, but their basal courses still protrude through the turf on the southern side, with a wall thickness of around 0.9 metres. The bank that marks the structure stands only about half a metre high. No date has been firmly attached to the building; it belongs to an indeterminate period, which is not unusual for smaller structures within cashels, where the absence of datable finds or documentary records leaves the archaeology silent on the question. The trapezoidal plan is an unusual detail worth pausing over, since it suggests the builder was responding to some constraint, perhaps the curve of the cashel wall nearby, or an earlier feature of the ground, shaping the house to fit rather than imposing a standard form.
