This is a rath, the Irish term for a ringfort, the most common monument type surviving in the Irish landscape. Ringforts were enclosed farmsteads, typically of early medieval date, built by a single family or small community. Most were defined by one or more circular banks of earth, sometimes reinforced with stone, and served as much as a marker of status and territory as a means of practical enclosure.

This particular example measures roughly 41 metres on its northwest to southeast axis and 55 metres on its southwest to northeast axis, giving it a noticeably oval rather than circular plan. The enclosing bank is wide, between four and five metres across, though it now stands only about 0.3 metres high, worn down over time by agriculture and weathering. On the northwest to east and southwest sides, a fosse, the shallow ditch dug to provide material for the bank, is still traceable at around four metres wide. The western side takes a different approach: rather than relying on an earthen fosse for definition, the bank here sits directly on the lip of a steep stream valley, using the natural drop of the land as its boundary. It is a small practical detail, but one that suggests the people who built the rath were working carefully with the contours of the ground rather than imposing a fixed template on it.
