It exists, as far as the documentary record is concerned, only as a shadow pressed into the grass, visible from above and invisible from the ground.

The site sits in reclaimed pasture roughly 340 metres west of a local road that runs along the townland boundary between Ballincolly and Garrynderk North. It was identified not by excavation or fieldwork but through aerial photograph analysis, a process by which archaeologists examine satellite and aircraft imagery for cropmarks, the faint discolourations in vegetation caused by buried features below the soil. A fosse, that is a defensive or boundary ditch dug into the earth, tends to retain moisture longer than the surrounding ground, which causes the grass or crop above it to grow slightly differently, and that difference becomes legible from altitude even when nothing is visible at eye level. In this case, Digital Globe orthoimages taken between 2011 and 2013, as well as Google Earth imagery, revealed a roughly circular cropmark approximately 27 metres in diameter. The shape is consistent with an enclosure of the kind associated with early medieval settlement in Ireland, though without excavation the date and function of the site remain unconfirmed. It was compiled by Martin Fitzpatrick and uploaded to the record in August 2021.

Because the site is not marked on historic maps and leaves no surface trace, there is nothing to see in the conventional sense if you visit the area. The field itself is working pasture. What makes the place worth knowing about is precisely that absence: it is a reminder that the Irish landscape still holds features that exist only in a particular quality of light, in a dry summer when cropmarks sharpen, on a screen where satellite data is stitched into something legible. The nearest practical reference point is the local road forming the Garrynderk North townland boundary, from which the site lies roughly 340 metres to the west.
