It is, however, a substantial structure: roughly 74 metres east to west and 70 metres north to south, making it large enough to have enclosed a significant settlement or farmstead in its day.

The enclosure is defined by a bank of earth and stone running from the south, around through the west, and continuing to the northeast. Where the bank gives way, a scarp, essentially a steep slope cut into the ground surface, takes over as the enclosing element. This combination of built bank and cut scarp is fairly typical of later prehistoric and early medieval enclosures in Ireland, where builders used whatever the local topography offered. A gap in the southern side may be an original entrance, though gaps of this kind can also result from later agricultural activity or the simple passage of people and animals over centuries. Hawthorn bushes have colonised the outer slopes of the bank and run along the scarp, which is common on earthworks that have been left undisturbed long enough for scrub to take hold. The site is in fair condition, meaning the essential form is readable even if the details have softened over time.
