This is a rath, the Irish term for a ringfort, the most common type of early medieval settlement monument found across the island. Tens of thousands once existed; many have been ploughed away or built over, which makes a well-preserved example like this one worth pausing over.

The enclosure measures 42 metres across in both directions, making it a reasonably substantial example of its kind. A stone-faced earthen bank, standing to a height of 1.7 metres, defines the circuit. Stone-facing on an earthen bank was a deliberate construction choice, lending stability and a degree of formality to what would originally have been a farmstead boundary, most likely dating to somewhere between the fifth and twelfth centuries. On the western to south-south-western arc, a fosse, or external ditch, runs outside the bank, dug to a depth of half a metre, the material from it likely used to build up the bank itself. There are gaps in the bank at the north-east, north-west, and south-south-west, at least one of which may represent an original entrance. The interior is slightly raised towards the north-west compared to the surrounding field, a subtle detail that suggests either deliberate construction or differential settling over the centuries.
