The feature measures roughly 45 metres north to south and 38 metres east to west, and is defined by a wide encircling bank somewhere between five and eight metres across. An enclosure of this type, a roughly circular or oval area bounded by an earthen bank, is a form found widely across Ireland, associated variously with early medieval settlement, ritual use, or agricultural activity, though assigning a function to any particular example without excavation is rarely straightforward.

The site sits on a short north-west to south-east drumlin ridge, the kind of low elongated hill formed from glacial deposits that gives the Monaghan landscape much of its lumpy, irregular character. The enclosure occupies the high ground at the ridge crest, a position that would have offered both visibility and a degree of natural drainage, both practical considerations for whoever first raised the bank. A later field boundary, running north-west to south-east, overlies the northern portion of the enclosure, cutting across it and confirming that the enclosure predates at least one phase of post-medieval land division. The site was first reported by Jean Charles Caillère, and its grass-covered bank remains visible on aerial imagery.
