It is, in fact, a ring barrow, a type of prehistoric funerary monument in which a burial or cremation deposit was placed within a defined enclosure rather than beneath a mound. The interior here sits slightly raised, roughly 0.3 metres above the level of the surrounding bank, which gives the whole structure an odd, inverted quality; the ground inside feels elevated rather than buried under anything obvious.

The site was recorded and compiled by Denis Power, with details uploaded in August 2011. The monument consists of a circular area roughly 16 metres in diameter, enclosed by a fosse, which is essentially a ditch, measuring around 0.65 metres wide and 0.3 metres deep. Outside that ditch sits an earthen bank, the internal face of which rises to about 0.7 metres, with a slightly lower external face of around 0.4 metres. The bank survives best from the eastern side running around to the northwest. There is no clear entrance gap, though a slight dip on the eastern side may hint at one. Ring barrows of this kind are generally associated with the Bronze Age, and while the Kilbreedy example has not been excavated, the form is consistent with monuments that elsewhere in Ireland have yielded cremated bone, pottery, and small personal objects.

The barrow sits in agricultural land in the Kenry barony of County Limerick, which means access will depend on landowner permissions, as is typical with field monuments of this kind across rural Ireland. Anyone making the effort to locate it should be prepared for rough going; the interior is covered with dense briar and furze growth, which makes close inspection difficult and the earthwork itself easy to misjudge underfoot. The ridge position is worth noting: even setting aside the monument itself, the elevated ground would have commanded a good outlook across the surrounding landscape, which may well have been part of its original significance.
