It is roughly rectangular, about 26 metres north to south and nearly 24 metres east to west, and its interior tilts gently downhill toward the east-northeast, covered over now with thistles and nettles. What defines it is a low inner scarp edge, surviving to a height of just 0.26 metres, running from the east-northeast to the southwest, with a dry-stone field boundary completing the circuit in the other direction. To a casual eye it might look like a slight dip in a grazing field, the kind of thing you would walk past without a second thought. But that regularity of shape, the way the boundary elements work together to enclose a space, marks it out as something deliberate.

Enclosures of this kind are found across Ireland and can date from prehistoric times right through the early medieval period. They served many purposes: farmsteads, ceremonial spaces, animal enclosures, or the platforms on which timber structures once stood. Without excavation it is rarely possible to say which category a given example belongs to, and this one at Conigar is no exception. What the record does note is the local geology: the site sits on a gentle east-facing slope in an area of outcropping limestone, and a disused quarry lies immediately to the east. The proximity of that quarry is worth keeping in mind, since the removal of stone over generations can alter the appearance of earthworks considerably, sometimes obscuring what remains, sometimes inadvertently preserving a boundary by drawing activity away from it. The site was recorded by Denis Power, with details uploaded in August 2011.

The enclosure sits in pasture, so access will depend on the landowner's permission, and the interior vegetation, nettles and thistles being the dominant cover, makes close inspection a matter of appropriate footwear and some patience. The low scarp is subtle enough that good, raking light, either early morning or late afternoon, will help pick out the slight change in ground level that defines the enclosure's edge. The adjacent quarry, though disused, is worth noting as a landscape feature in its own right, a reminder that this corner of Limerick has been worked and reshaped across many centuries, and that what looks like empty countryside rarely is.
