The enclosure measures roughly thirteen metres across and is defined by a bank of earth and stone that rises to about half a metre, with a deliberate break on the eastern side. That gap in the bank is the kind of detail that tends to catch an archaeologist's eye, suggesting an original entrance rather than simple collapse or erosion over time.

The enclosure sits approximately fifty metres to the north-east of a wedge tomb, a type of megalithic burial monument built during the late Neolithic or Early Bronze Age, typically consisting of a roofed stone gallery that narrows or "wedges" toward one end. The proximity of the two features is notable. County Cork has a substantial concentration of wedge tombs, and it is not unusual in Irish archaeology to find later enclosures positioned near older monuments, sometimes reflecting a continued significance attached to a place long after its original use had ended. Whether the enclosure at Kilberrihert is broadly contemporary with the tomb, or represents activity from a completely different period, is not recorded. Small circular earthwork enclosures of this kind appear across Ireland in contexts ranging from the Bronze Age to the early medieval period, which makes attribution without excavation largely a matter of guesswork.

The source material for this site is thin, and the enclosure has attracted little detailed attention beyond its basic recording. What remains is a modest ring of earth and stone beside an ancient tomb, the two of them occupying the same patch of mid-Cork ground with no obvious explanation for the relationship between them.
