Its outline is trapezoidal, broader at the north end and narrowing toward the south, measuring roughly 36 metres from north to south and tapering from 32 metres wide down to 17. The western edge is defined not by any man-made boundary but by the cliff itself, while the remaining sides are enclosed by a low bank of earth and stone, about 2.3 metres wide and a metre high. There are faint suggestions of a fosse, an outer defensive ditch, along the north-eastern edge, though no original entrance has been identified.

The site was recorded during an Irish Tourist Association survey carried out between 1942 and 1944, one of a series of systematic local surveys conducted across Ireland during the mid-twentieth century. Beyond that documentation, the enclosure's age and function remain uncertain. Enclosures of this general type in Ireland range from early medieval ringforts to earlier prehistoric enclosures, but without excavation or dateable surface finds, no period can be confidently assigned here. What complicates matters further is a detail noted in the north-eastern quadrant: an irregularly-shaped depression, up to six metres across and about 0.7 metres deep, whose significance was not understood by those who recorded it and remains unexplained. It could represent a collapsed interior feature, a later disturbance, or something else entirely.
