It is easy to overlook, especially because the enclosure surrounding it already demands attention, but the mound is recorded as a distinct feature in its own right, separate from the earthwork that contains it.

The enclosure is a univallate rath, meaning it is defined by a single circuit of bank, in this case composed of earth and stone. Raths of this kind are among the most common field monuments in Ireland, generally associated with early medieval settlement, serving as enclosed farmsteads or places of habitation between roughly the fifth and twelfth centuries. The rath at Kilcock sits on pastureland immediately south of a property known as Lynch's house, and it is within the northern sector of this enclosure that the small interior mound appears. Whether it represents a collapsed structure, a deliberate earthen feature, or something else entirely is not recorded, and its precise function remains open. Such interior mounds within raths are not unknown, but they are far from routine, which is part of what makes this one worth noting.
