The collapsed stone fortification, originally about 2.2 metres wide and rising to over half a metre in places, retains sections where both the inner and outer wall faces stand up to three courses high. The site offers sweeping views across the surrounding landscape, its strategic position on rocky outcrop clearly chosen for defensive advantage.

The most intriguing feature lies hidden in the southeastern sector of the interior, where a largely filled souterrain runs beneath the surface. This underground passage, oriented from east-northeast to west-southwest, stretches just over 5 metres in length and reveals itself as a depression in the ground that widens from 85 centimetres to 2 metres at its western end. A single roof slab remains visible in the depression, hinting at the subterranean chamber below, which measures 1.1 metres across at its top. The eastern end of the souterrain appears to extend beneath the cashel wall itself, suggesting it may have served as a concealed entrance or escape route.

Adding to the site's complexity, a discontinuous line of stones encircles the cashel wall at a distance of 21 metres on the northern side, positioned 6 to 7 metres below the level of the main fortification. Whether this represents an outer defensive wall, a livestock enclosure, or some other structural feature remains uncertain, but it demonstrates the sophisticated planning that went into this ancient settlement. The entire complex speaks to the ingenuity of Ireland's early inhabitants, who carved out secure homesteads in the landscape whilst maintaining hidden passages for storage, refuge, or escape.
