It is easy to miss, and easy to misread as a natural feature or a collapsed field boundary, yet the regularity of its form tells a different story.

This subcircular enclosure, measuring 19.3 metres north to south and 18 metres east to west, belongs to a category of monument found across Ireland whose precise function often resists easy definition. Earthen enclosures of this kind are generally associated with early medieval settlement, the enclosed area once serving as a farmstead or small defended residence, though some examples have ritual or funerary associations that only excavation can confirm. The bank here survives in fair condition, and the choice of a hill summit for its location is consistent with the practical logic of early Irish settlement, offering visibility across the surrounding landscape. At some later point, a field wall was constructed directly against the outer face of the bank, running from the south-east, around through the south, and continuing to the north-west. This kind of secondary reuse is common, later farming communities finding a ready-made boundary to build upon without any particular awareness of, or concern for, what lay beneath. A gap on the eastern side appears to be a modern interruption rather than an original entrance.
