Look more carefully and the geometry gives it away: a roughly oval enclosure measuring about 36.5 metres north to south and 47.5 metres east to west, shaped by a combination of an earthen bank and a scarped edge, the latter being a deliberately cut and shaped slope rather than a built-up wall. Around parts of the northern and eastern perimeter runs an external fosse, a shallow ditch that would once have reinforced the boundary, now sitting at about 0.6 metres deep and 2.5 metres wide. The interior is level and grassed over, with trees growing along the north-western to east-north-eastern stretch of the perimeter, giving that arc of the enclosure a slightly wooded character that sets it apart from the open pasture within.

The enclosure sits roughly 50 metres north-east of the site of Kilmurry Church, a proximity that raises quiet questions about the relationship between the two. Ecclesiastical enclosures of this kind are not uncommon in Ireland, where early Christian settlements were often defined by a circular or oval earthen boundary, and a church and its associated enclosure frequently occupied slightly elevated ground for both practical and symbolic reasons. The earthwork here has not been undisturbed: the scarp has been quarried at the south end and, to a lesser degree, at the north. A linear field boundary cuts across the base of the scarp and bank along the western to northern stretch, truncating the fosse in the process. A field boundary that appeared on the 1923 Ordnance Survey six-inch map, abutting the scarp at the east, has since been removed. The record was compiled by Denis Power and uploaded in August 2011.

The site sits in working farmland, and a farm trackway skirts around the southern and eastern sides, which means the enclosure is at least approachable without having to cross open fields. The interior, being level and under pasture, reads clearly once you are at the perimeter, and the combination of bank, scarp, and ditch is most legible on the northern and eastern sides where the fosse has survived intact. The quarried sections at the south make the profile there less coherent, but the overall oval shape remains readable from the ground. As with many earthworks of this type, there is no interpretive signage; what you are looking at requires a little patience and a willingness to read the ground itself.
