The enclosure at Killoughty measures roughly 65 metres along its northwest to southeast axis and 50 metres across, making it a substantial feature, one that would have been immediately legible to anyone who knew what they were looking at, yet easy enough to walk past without a second thought.

What makes this site genuinely interesting is the variation in its boundary. An enclosure of this kind, a roughly circular or oval area defined by a raised or scarped edge, is the most common type of early medieval monument in Ireland, used variously as a farmstead, a place of assembly, or a minor ecclesiastical site. What survives here, recorded by Denis Power and uploaded to the national record in August 2011, is not uniform. The northern to southeastern stretch of the perimeter is defined by a relatively modest scarped edge, just 0.2 metres high and about a metre wide. The southern to northern section, however, is markedly more substantial, with a scarp rising to 1.4 metres and nearly two metres wide, accompanied by an external fosse, a shallow ditch running along the outside, 0.6 metres deep and 1.5 metres wide. This asymmetry suggests the site may have been more heavily defended or more deliberately bounded on one side, perhaps responding to the natural slope or to a perceived direction of approach. A further complication: this more pronounced southern section has been absorbed into a later north-south field boundary, and a short stretch of the original feature has been removed just north of the site, the kind of quiet attrition that has claimed countless such monuments across the Irish countryside.

The interior is level and under pasture, which means there is little to see at ground level beyond the undulation of the earthworks themselves. The north-facing slope means the light tends to be flat rather than raking, so the scarped edges show up best on overcast days or in low morning light when shadows gather along the fosse. There is no formal access or signage, so locating the enclosure requires consulting the Sites and Monuments Record for its precise coordinates before visiting. As with most earthwork sites of this kind, the best approach is simply to walk the perimeter slowly, paying attention to the change in scale between the two sections of boundary, where the modest northern scarp gives way to the much heavier southern earthwork and its accompanying ditch.
