What makes it quietly anomalous is the evidence of what happened after it was built: the eastern half of the interior has been quarried away, and where the ground was cut back, burnt stone and dark soil are visible along the south-eastern edge. That kind of scorched, carbon-stained earth is often associated with fulachta fiadh, ancient cooking or processing sites where water was heated by dropping fire-heated stones into a trough, though whether that is the explanation here remains uncertain.

The enclosure measures roughly 17.5 metres on its north-east to south-west axis and 16.8 metres across, making it a modest but carefully defined space. A gap in the bank at the western corner may represent an original entrance, or it may simply be a point where the structure was disturbed over time. Rectangular enclosures of this kind are found across Ireland and can be difficult to date without excavation; they may be early medieval in origin, or associated with land management and settlement at various periods. The quarrying that removed the eastern interior was likely carried out in the post-medieval period, a practical extraction of loose stone and material that incidentally opened a cross-section through whatever deposits had accumulated inside.
