What makes it quietly odd is how its own description has shifted over time: the first edition of the Ordnance Survey six-inch map shows a roughly oval shape, approximately thirty metres by twenty metres, planted with trees, the kind of neat intervention that suggests deliberate human arrangement. By the time the third edition was surveyed in 1932, that oval had resolved itself, on paper at least, into a circle of roughly thirty metres across. On the ground today, the shape is vaguer still, reduced to faint traces of a roughly circular band of vegetation about thirty-five metres in diameter, curving around the foot of the hillock from the east, through the south, and round to the west.

The site sits within what was once demesne land, the privately managed agricultural and ornamental grounds attached to a large house or estate. That context matters here, because it shapes the most likely explanation for what this feature actually is. Surveyors have cautiously described it as possibly a landscape feature rather than an ancient enclosure in the archaeological sense, meaning it may have been planted and shaped as part of deliberate estate improvement, a common practice across Irish demesnes from the eighteenth century onward, when landowners regularly imposed formal geometry onto the land around their houses. The shift in its mapped outline over successive surveys could reflect the way planted trees and shrubs grow, merge, and obscure original boundaries, or it could simply reflect different surveyors making different judgements about what they were recording. The fact that trees were noted on the earliest map is suggestive; enclosures planted with trees on low hillocks within demesnes were sometimes designed as eye-catchers or ornamental features in the landscape, visible from the house at a distance.
