The surrounding bank, which defines its roughly circular shape, swells from just four metres wide on the eastern side to ten metres at the north-west, a discrepancy that speaks to centuries of agricultural habit rather than original design.

A rath is an earthen ringfort, a form of enclosed farmstead built throughout Ireland roughly between the fifth and twelfth centuries. Thousands survive across the country in varying states of preservation, but each tends to carry its own small peculiarities. Here, the bank is composed of earth and stone, and traces of inner stone-facing remain visible at the southern arc, suggesting a more deliberate construction beneath what has accumulated over time. That north-western bulge is explained by generations of field clearance: farmers piling removed stones against the existing bank, gradually thickening it until it became something quite different from what it once was. The enclosure measures approximately 37 metres east to west and 34 metres north to south. Inside, the ground is largely featureless, save for one detail: a small circular cairn, roughly two metres in diameter, sitting in the western half of the interior. Its relationship to the rath is uncertain, but it is considered possibly associated, which in archaeological terms means it is interesting enough to note and unexplained enough to leave open.
