A cashel is a stone-walled enclosure of early medieval Irish origin, typically circular and built without mortar, and this one measures nearly thirty-seven metres across its widest axis. O'Donovan recorded walls standing seven feet high on the outside, eight feet thick at the top, and built from very large, well-shaped stones with a pronounced batter, meaning the walls lean inward slightly as they rise. He also noted a souterrain, an underground passage or chamber common to early medieval Irish sites, though even then it was impossible to enter on account of the narrowness of the passage.

By the time the antiquarian Thomas Westropp examined the site in the 1890s, he found finely fitted masonry still intact on the outer face, though the inner face had sustained damage. He also found the souterrain closed, a change from O'Donovan's time. Today the cashel remains well preserved, its roughly circular drystone wall still largely legible, though the interior has no visible entrance and the souterrain is blocked. A spread of collapsed stone several metres wide surrounds the standing wall, and a cell has been built onto the wall at the south, with part of the wall nearby having been rebuilt at some point. The outer face is generally visible; the inner face only partially so. Sitting near the foot of a south-facing slope, the enclosure commands good views to the east, south-east, and west.

The cashel does not stand entirely alone in the landscape. Some thirty-seven metres to the north lie the recorded sites of a tau cross and a cross fragment, a tau cross being T-shaped rather than the conventional Latin form, and around seventy-seven metres to the north-west is the site of a former gateway. These associated features suggest the cashel was once part of a broader complex, though precisely what kind remains an open question.
