The rath, as this type of earthwork is known, is a roughly circular enclosure defined by an earthen bank, the kind that once formed the defended farmstead of an early medieval Irish family. This particular example measures twenty-eight metres in diameter, with its bank, standing about 1.3 metres high, still visible to the east, south, and west. It is the northern side where things get more complicated.

A field drain runs outside the enclosure and concentric to the bank, and it has cut across the northern arc, effectively truncating that part of the circuit. Writing in 1939, P. J. Hartnett observed that material excavated from this drain had been used to construct a separate east-west bank, which now closes off the interior on the northern side. The result is a slight confusion of earthworks, where land management over the centuries has quietly rearranged the edges of a structure that was already ancient when the drain was first dug. Also recorded within the interior is a possible souterrain, the term for an underground stone-lined passage typically associated with ringforts, used variously for storage or refuge. Whether this one survives intact beneath the pasture is unclear from what has been recorded at ground level.
