Locally it is called the Lisheen, a diminutive of the Irish word lios, meaning a ringfort or enclosure, the kind of term that tends to survive in townland memory long after the structure itself has become difficult to read in the landscape. What survives here is subtle: a D-shaped area roughly 30.5 metres on its longer axis, sitting on a gentle rise in undulating ground, its curving side defined by a low scarp with an external fosse, which is a shallow defensive ditch, and its straight side formed by a field fence running alongside a road.

The enclosure appears on the 1838 Ordnance Survey six-inch map as a rectangular shape, but by the 1916 edition it is recorded as the rougher D-form that can still be traced on the ground. When the antiquarian Knox visited in 1911, he described a slightly raised earthwork defined by a slight bank with an external fosse and what he called a trivial bank on the outside. The current dimensions place the scarp at roughly 2.6 metres wide with an external height of around 0.9 metres, and the fosse between 1.8 and 2 metres wide, though it survives now only as a faint depression, most legible along the northern and eastern arc and fading away towards the south. The interior is very slightly raised above the surrounding pasture. Notably, the road running along the south-western side sits at a comparable elevation to the interior, which has led to the suggestion that the road may have cut through and removed the western half of the enclosure at some point, leaving the present D-shape as a remnant of what was originally a more complete circular or oval form.

Hazel and blackthorn have colonised the perimeter and begun to encroach inward, which at least has the effect of marking the outline in a way the earthwork itself no longer clearly does from a distance. The slight bank, the barely-there ditch, the raised interior, and the hedge-line of scrub together reward a slow circuit on foot rather than a glance from the road.
