It exists, as far as direct observation goes, only from the air, revealed as a cropmark, the kind of ghostly outline that appears in growing grain or grass when buried features beneath the soil affect how plants draw moisture and nutrients. In dry summers, the difference becomes visible from above as a ring of subtly darker or lighter vegetation. On the ground, in undulating tillage country, there is nothing to distinguish the spot.

The feature was recorded from an aerial photograph taken on 15 July 1970, part of the Cambridge University Collection of Aerial Photography. It shows a roughly circular enclosure approximately 30 metres in diameter. Ring-ditches of this kind are generally the ploughed-down or eroded remains of prehistoric burial or ritual monuments, often Bronze Age in origin, where the original earthen bank and inner ditch have been reduced over millennia of cultivation to little more than a soil anomaly. What makes this particular spot quietly remarkable is the density of related features in the immediate landscape. Within 160 metres or so, there are at least three other enclosures of different types, as well as a ringfort to the west. A ringfort, to give it its due, is a type of enclosed farmstead typical of early medieval Ireland, usually defined by a bank and ditch, and used for settlement rather than burial. The clustering here suggests a landscape that was repeatedly occupied and modified across a very long span of time, with each generation leaving its own faint impression in the soil.
