Roughly eight metres across and only slightly raised above the surrounding pasture, it sits in gently undulating land to the south-west of the river, drier than everything around it in a way that suggests something deliberate lies beneath the surface. It is the kind of feature that a farmer would notice long before an archaeologist did.

What exactly was built here, and by whom, is not recorded. The classification as an earthwork places it in a broad category of human-made landscape modifications, anything from the remains of a ringfort (a circular enclosure used as a farmstead, common across early medieval Ireland) to a burial mound or the foundation of a long-vanished structure. The circular form is suggestive, and the modest diameter falls within the range of smaller domestic enclosures, but without excavation the site keeps its own counsel. Its position close to the Laune, a river that drains Lough Leane and runs westward toward Killorglin, would have made this low-lying ground both useful and awkward, fertile but prone to flooding, and the slight elevation of the feature may reflect a deliberate effort to claim a dry foothold in an otherwise difficult field.
