The earthwork is roughly circular, measuring about 27.8 metres north to south and 30 metres east to west, and what defines it is a scarped, or cut-away, edge rather than a built-up bank. That distinction matters: a cashel, strictly speaking, is a ringfort whose enclosing boundary was originally built from stone rather than earth and timber, and the researcher Wardell identified this site in those terms. Whether the stone was robbed out over centuries or whether the scarp itself was always the primary feature, the remains are modest enough that most walkers would cross the field without a second thought.

Ringforts, sometimes called raths when earthen and cashels when stone-built, were the dominant form of rural settlement in early medieval Ireland, typically associated with the period between roughly the fifth and twelfth centuries. They served as enclosed farmsteads, protecting a family, its livestock, and its stores. This particular example sits on a gentle north-east-facing slope, a positioning that would have offered reasonable drainage while keeping the enclosure visible across the surrounding landscape. The interior is uneven under its present pasture cover, and a small depression in the north-east quadrant, measuring roughly 0.7 metres by 0.75 metres and about 0.35 metres deep, hints at some subsurface feature, possibly the collapse of a souterrain, which is an underground stone-lined passage often built beneath ringforts for storage or refuge, though no excavation has confirmed this. The notes compiled by Denis Power record the scarp as best preserved along the eastern to south-eastern arc, where it reaches a height of 0.5 metres and a width of about 2.65 metres.

The site sits in working farmland, so access depends on landowner permission and the practical realities of a grazed field. The earthwork is subtle enough that visiting in late autumn or winter, when grass growth is lower, gives the clearest sense of the scarped edge and the slight unevenness of the interior. The north-east quadrant depression is worth locating carefully once you are inside the enclosure, as it is the one feature that suggests something more complex once lay beneath the surface. The place name Oldabbey in the townland adds its own layer of interest, pointing to ecclesiastical remains in the vicinity that may well have had some relationship, temporal or spatial, with the earlier secular settlement represented by the cashel.
