The enclosure measures roughly 46 metres across, and what survives is a scarp, essentially a cut or slope in the ground rather than a raised wall, rising to about 1.3 metres along the arc from the north-west to the south-west. A slight internal lip on the northern side may be the remnant of a bank that once crowned or accompanied that scarp, suggesting the boundary was originally more substantial than what the land now shows.

Enclosures of this kind are among the most common, and most quietly puzzling, features of the Irish archaeological landscape. They are often associated with the early medieval period, when ringforts, circular enclosures defined by earthen banks and ditches, served as farmsteads and high-status settlements across the country. The relationship between a settlement and its surrounding wetland was rarely accidental; marshland offered natural protection on exposed sides, reducing the need for elaborate artificial defences. Here, marsh lies immediately to both the north and south, which may explain why the scarp is most clearly defined along the western arc, where the ground offered no such natural barrier. A gap of about three metres to the east-south-east would have served as the entrance. The interior surface is uneven, and on the western side it sits level with the surrounding field, giving the impression from that angle that the enclosure has almost dissolved back into the ordinary pasture around it.
