The feature is raised and partially levelled, measuring around 32 metres across, and retains a low, eroded bank along its eastern side that still reaches about 0.6 metres in internal height. What makes it quietly interesting is less the enclosure itself than what it implies: this is not an isolated earthwork but a fragment of something larger and more complex that has largely dissolved back into the landscape.

The enclosure appears to be one component of a deserted settlement, a category of site found across Ireland where communities that once farmed, traded, and built in a place simply ceased to do so, leaving behind only earthworks and archaeology to suggest their presence. At Moonhall, the broader complex of earthworks associated with this abandoned settlement wraps around a castle that stands approximately 100 metres to the north. The relationship between the enclosure and the castle suggests a functioning community once organised itself around that structure, with the enclosure potentially serving a domestic or agricultural role within the wider settlement layout. The gradual slope of the interior from south to north, and the marshy ground surrounding it, give some sense of the working conditions that shaped life here.
