What makes it worth pausing over is partly the survival of its form, and partly one small anomaly: the drystone facing on its north-western exterior, set nearly vertical against the bank, which archaeologists consider probably not original. Someone, at some point after this structure was first raised, chose to reinforce or alter that stretch of wall. When, and why, is not recorded.

The site is a rath, the Irish term for a roughly circular enclosure defined by an earthen bank and, sometimes, a fosse, which is simply a ditch dug around the outside to provide material for the bank and an additional line of defence. Raths were the everyday farmsteads of early medieval Ireland, typically occupied between the fifth and twelfth centuries, and thousands survive across the country in varying states of preservation. This one measures 32.7 metres in diameter across the enclosed area, with a bank seven metres wide. The bank itself is notably asymmetrical in height, rising to around 0.8 metres internally on the north-eastern side and to 1.5 metres on the south-western, while the external face reaches between 1.8 and 1.9 metres. A fosse, now slight and measuring about 1.4 metres wide, is visible on the north-western arc. The entrance gap, 4.2 metres across, faces south-east, an orientation that would have caught morning light and offered a practical view down the slope. No traces of internal structures have been identified within the enclosure.
