The feature leaves no surface trace worth speaking of; what reveals it is the differential growth of crops above buried soil disturbance, patterns legible only from above, in the right season, in the right light. These cropmarks, picked up on satellite imagery, outline a roughly oval space measuring approximately 45 metres north to south and 50 metres east to west, defined by an inner and outer fosse. A fosse, in this context, is simply a ditch, usually the defining element of a ringfort or similar enclosed settlement, and the presence of two concentric ones here suggests something that was either well defended or socially significant, possibly both.

The enclosure was identified and reported by Jean-Charles Caillère, whose reading of aerial and satellite imagery brought it to light. The Brackford river runs roughly east to west about 80 metres to the south, and a smaller stream, itself only visible as a cropmark, passes immediately south of the enclosure. Water proximity was a practical consideration in early Irish settlement, and the positioning here fits a familiar pattern. What makes this particular spot quietly remarkable is the density of enclosures in the immediate area. A second enclosure lies approximately 145 metres to the north-north-west, and a third sits around 130 metres to the west-south-west. Three related features within such a compact area, none of them visible to the naked eye on the ground, point to a landscape that was once considerably more organised and inhabited than its current appearance suggests.
