The boundaries are not accidental; they follow the ghost of a ringfort, a type of circular enclosed settlement common across early medieval Ireland, typically defined by one or more earthen banks and ditches. Here, the enclosure survives only as a faint circular rise in the pasture, roughly 56.5 metres in diameter, with a shallow depression running along its outer edge where the original bank material was once piled high enough to matter.

According to P. J. Hartnett, writing in 1939, the ringfort was levelled around 1910, which places its destruction in a period when agricultural improvement frequently won out over earthworks that had survived for perhaps a thousand years. The nearby house is called Old Fort, a name that suggests the monument was a recognisable local landmark long before it was dismantled. What remains today is the kind of archaeology that rewards attention rather than spectacle: a low swell in a grazing field, a slight hollow, and the peculiar logic of field walls that converge on a point no farmer would have chosen for purely practical reasons.
