It cannot be seen from the ground at all. The only evidence of its existence came from the air, when a cropmark revealed the outline of a fosse, which is a defensive or boundary ditch, pressed faintly into the soil. Cropmarks form when buried features alter how moisture and nutrients move through the ground, causing the crops or grasses above them to grow slightly differently, and so betray what lies beneath. It is a quiet kind of archaeology, legible only under the right conditions and only from altitude.

The enclosure was identified on an aerial photograph taken on 14 July 1970, part of the Cambridge University Collection of Aerial Photography. What the photograph shows is not the full structure. Only the southern portion survives as a readable feature, measuring approximately 40 metres, with the southern side running on a NW-SE alignment and the lower sections of both the eastern and western sides also visible. The northern part of the enclosure has not survived intact, having been cut through by the Kilkenny to Waterford railway line, which effectively erased that portion of the feature. The shape of what remains is straight-sided rather than the circular form more commonly associated with early Irish enclosures, which makes this a slightly unusual example. Straight-sided enclosures can suggest different periods or functions, though without excavation it is not possible to say more about its age or purpose.
