No wall rises above the turf, no obvious earthwork announces itself. What survives is a fosse, essentially a ditch dug to define and defend a boundary, along with a possible outer bank, and the whole arrangement only becomes legible from the air, where it reads as a cropmark, the differential growth of grass or grain above buried features that reveals buried archaeology to aerial cameras.

The enclosure measures roughly 30 metres north to south and 38 metres east to west, an oval shape that is characteristic of a broad class of Irish enclosed sites spanning from the prehistoric period through to the early medieval. Such enclosures could have served as settlement sites, livestock enclosures, or places of ritual significance, though without excavation it is impossible to say which purpose, or combination of purposes, applied here. The choice of a natural hillock is telling; elevated ground offered both practical advantages for drainage and visibility, and may have carried symbolic weight in how communities organised and presented themselves within a landscape. The site came to wider attention through aerial photography carried out on 2 August 1996, which captured the cropmark pattern clearly enough to allow the enclosure's dimensions and rough form to be mapped.
