It has no visible entrance, no trace of internal features, and no obvious sign of what it was once for. That combination, a substantial enclosure with clear effort put into its construction and yet no legible purpose left behind, gives the site an quietly unsettling quality that sets it apart from the more straightforwardly interpretable ringforts and enclosures scattered across the Irish landscape.

The enclosure measures roughly 80 metres on its northeast to southwest axis and 89 metres east to west, making it a considerable structure. It is defined by an earthen bank between four and six metres wide, which still stands between 0.4 and 1.2 metres high on its interior face and up to two metres on the exterior. A fosse, meaning a defensive or boundary ditch, runs around the northwest and southern sides to a width of four metres and a depth of 1.2 metres, with faint traces surviving at the northeast. At some point the northeast perimeter was given a dry-stone facing, a later addition that suggests the site remained in use or at least in someone's awareness long after its original construction. A farm track has since cut through the northeast section and now occupies what was the recut fosse at the northwest, blurring that portion of the earthwork further. Sitting just outside the enclosure to the north is a large block of quartz-granite known locally as the Mass Rock, a name that points to the Penal era, when Catholic worship was banned under British law and congregations gathered at outdoor stones in remote spots to hear Mass celebrated in secret. Whether the rock's proximity to the enclosure is coincidental or whether the existing earthwork offered some practical shelter or concealment is an open question.
