What appears to be a slight irregularity in the field is in fact the remnant of a rath, a roughly circular earthwork enclosure of the kind built across Ireland during the early medieval period, typically serving as a farmstead and status marker for a farming family of some standing. This particular example measures approximately 45 metres east to west and 40 metres north to south, making it a reasonably substantial example, though very little of it now reads clearly as a constructed thing.

The surviving elements are modest. Along the eastern and south-eastern arc, a low bank of earth and stone persists, roughly 3.4 metres wide but only 0.3 metres high, worn down by centuries of agricultural use. On the north-western to northern side, the enclosure is defined by a low scarp of similar height rather than a built bank. Just visible at the south-east is a trace of an external fosse, the shallow ditch that would originally have run around the outside of the bank, here measuring about 2 metres wide and barely 0.1 metres deep. Across the southern, western, and north-western stretch, the original perimeter has been absorbed almost entirely into the straight lines of later field boundaries, which have overwritten and rearranged the older form. The original entrance has been lost completely, leaving no indication of where people once passed in and out of this place.
