A roughly polygonal or subcircular outline, spanning approximately 250 metres from northwest to southeast, can be traced across the landscape through a combination of field fences and field drains. The arc runs from the southeast around to the north, where straight and gently curving boundaries follow what may, or may not, be a far older line. The eastern side is defined by a single straight drain. Taken together, these elements describe the shape of an enclosure, though whether that shape is the product of ancient intention or accumulated agricultural accident remains genuinely unclear.

Enclosures of this kind, when they are ancient, are typically associated with early medieval settlement or ceremonial use in the Irish landscape, sometimes functioning as raths or ringforts, sometimes serving purposes that have left no other trace. The roughly 250-metre diameter here would make this an unusually large example if it does turn out to be prehistoric or early historic in origin. That said, the features defining it, field banks and drainage channels, are exactly the kind of infrastructure that post-medieval and modern farming has laid down across the Irish countryside in overlapping generations, often following the contours of slightly elevated ground for entirely practical reasons. The outline appears on the 1931 Ordnance Survey six-inch map, which places it firmly in the modern record, but does not itself resolve the question of how long those boundaries have been there or what, if anything, they replaced.
