Aerial photographs reveal a circular area roughly forty metres in diameter, its outline betrayed by a difference in vegetation rather than any obvious rise or depression in the ground. This kind of cropmark or vegetation mark occurs when buried features, in this case a single narrow enclosing ditch, affect the moisture and nutrient levels available to plants growing above them, producing subtle tonal differences that only become legible at altitude.

A rath, to use the Irish term, is an enclosed farmstead of the early medieval period, typically defined by one or more earthen banks and ditches and associated with a single family or household. Thousands survive across Ireland in varying states of preservation, but this particular example sits on level ground and has fared less well in the visible landscape. The narrow ditch that once defined its perimeter appears to have been at least partially cut across by a field bank running northeast to southwest along its southern edge, suggesting the agricultural reorganisation of the land over the centuries gradually obscured and encroached upon the original enclosure. What remains readable on the ground has been, in effect, absorbed into later field patterns.
