A rath, to use the Irish term, is a type of early medieval enclosed farmstead, typically circular, defined by one or more earthen banks and ditches. This one is roughly 34.6 metres across, with an inner bank that still stands nearly 1.75 metres high on its outer face at the north-west, and a surrounding fosse, or ditch, that remains traceable as a shallow depression on the western arc. A modern laneway cuts directly across the fosse and outer bank on one side, and a field wall clips the outer slope to the east, but enough survives to read the original form without much effort.

The site carries a quietly troubling layer of local memory. A field inspection in 1982 recorded a tradition that the rath had been used as a children's burial ground. These informal burial places, sometimes called cillíní, were used in parts of Ireland for unbaptised infants and others excluded from consecrated ground, a practice that persisted well into the twentieth century. Whether that tradition here refers to something medieval or far more recent is not recorded. The same 1982 inspection noted a gap of about three metres in the bank at the south-east, which may mark the position of the original entrance, though by a follow-up visit in 1996 it had disappeared entirely under overgrowth. That 1996 inspection also found two freshly dug trenches inside the enclosure, one over seven metres long, their origin and purpose unrecorded. A second rath lies just 175 metres to the south, suggesting this part of the Mayo landscape was once more densely settled than its present suburban-edge appearance implies.
