It is a rath, the most common type of early medieval enclosure in Ireland, typically a circular area ringed by an earthen bank and an outer ditch, and used as a defended farmstead, probably between the sixth and twelfth centuries. What makes this one worth pausing over is the detail still visible in the ground: an enclosing bank that reaches two metres in internal height along its best-preserved northern to south-western arc, and a shallow outer fosse, the ditch that once threw the bank into sharper relief, that deepens deliberately along the south-western quadrant to serve as a drain. Someone, at some point, made a considered engineering decision about water management. The entrance, two metres wide, faces north.

Inside the enclosure, the ground is not blank. Cultivation ridges, the low parallel corrugations left by spade or plough tillage, run across the interior on a roughly north-south axis. These ridges suggest the space was worked as farmland at some stage, either during the original occupation of the rath or in a later period when the enclosure's banks were simply a convenient boundary for a field. The overall dimensions, thirty-three metres north to south and twenty-nine metres east to west, place it in the middle range for a site of this type. It is roughly circular rather than precisely so, which again is entirely typical; most raths were laid out by eye and local need rather than by any exact geometry.
