What makes it quietly arresting is not its scale, which is modest at around thirty metres in diameter, but a single piece of local lore attached to it. When a tree growing in the interior was felled, a broken stone cross-head was found lodged within its trunk. That cross-top now rests beside the castle house nearby, its origins folded into the wood-grain of a tree that had been growing over it, possibly for generations.

The enclosure itself takes the form of a scarp, an earthen slope or bank cut into the ground rather than built up, rising to a maximum height of about 0.9 metres, with a gap opening to the north. The interior slopes gently down toward the centre, a detail that sometimes points to earlier, longer use of a site, whether as a ringfort, a small enclosure for livestock, or something with a ritual or boundary function that no longer survives in the record. Ringforts, the most common class of early medieval enclosure in Ireland, were typically used as farmsteads between roughly the fifth and twelfth centuries, though circular enclosures of this kind can predate or postdate that period considerably. The broken cross complicates the picture without resolving it; a stone cross within or near an enclosure might suggest ecclesiastical association, or simply that the site was repurposed at some point after its original use had been forgotten. The trees and undergrowth that have colonised both the scarp and the interior make it difficult to read the ground with any clarity now.
