Set at the break of slope on the western side of a ridge in County Mayo, the earthwork looks out over a broad, low-lying stretch of terrain to the west and north-west, with a stream running about 200 metres to the west. The positioning is deliberate: whoever constructed this enclosure understood that the natural contours of the hillside could do some of the defensive work for them.

A ringfort, or rath, is an early medieval enclosure, typically circular, formed by an earthen bank and ditch and used as a farmstead or a place of status. This one follows the type closely: a roughly circular raised platform, approximately 39 metres north to south and 36.5 metres east to west, defined by an interior scarp that rises to 2.7 metres on the western side. Beyond that scarp lies a fosse, a defensive ditch about 3 metres wide, and then an external bank roughly 6 metres across with an external height of 2.7 metres. Where the fosse and bank align with the natural ridge slope, they have been cut into the hillside so that the fosse reads almost as a terrace, and the outer bank merges into the falling ground below it, making the whole construction appear more formidable from the west than its earthwork dimensions alone would suggest. This integration of artificial and natural topography is what sets the site apart from more straightforwardly constructed raths. The surviving elements are concentrated between the south-west and north-west arcs; elsewhere, a section of the scarp to the north has been levelled and the south-east arc has been absorbed into a field boundary over time.

The interior today is level and grassy, with no visible features and no clearly defined original entrance. Hawthorn, blackthorn, and brambles have colonised the scarp and outer bank, which is a common fate for ringfort margins across Ireland, the scrub providing a kind of accidental preservation by discouraging the plough.
