The ringfort here is a raised enclosure roughly 44 metres across, its defining bank still standing to an internal height of around 2.12 metres and an external height of approximately 2.4 metres. That a mound of compacted earth and rubble thrown up perhaps twelve or thirteen centuries ago should survive at those dimensions, in farming country, is quietly remarkable.

Ringforts, known in Irish as raths when formed from earthen banks rather than stone, were the typical enclosed farmsteads of early Christian Ireland, dating broadly from the period between the fifth and twelfth centuries. Most were single-family settlements, the enclosing bank serving to define territory and provide some protection for livestock rather than functioning as a serious military fortification. Thousands were built across the island, and thousands have since been levelled by ploughing, drainage work, or simple neglect. The Aghenderry example has fared better than many, retaining enough of its original profile to give a clear sense of the original structure's intention and scale.

A farmyard sits immediately to the south of the earthwork, and a public road passes along the southeast sector, which means the monument exists in close proximity to the working rhythms of the present day. That adjacency is not unusual for surviving ringforts, which often endured precisely because local farming activity accommodated rather than obliterated them, but it does mean the site reads as something folded into ordinary rural life rather than set apart from it.
