No earthwork, no wall, no boundary stone. Whatever was once here has long since flattened into the surrounding fields, leaving nothing that a walker would notice. The only reason anyone knows it was there at all is a single aerial photograph taken in August 1984.

That photograph, taken during an aerial reconnaissance flight, caught a cropmark, the faint differential in vegetation growth that sometimes betrays buried or long-vanished structures to a camera overhead. What it revealed was a narrow band of slightly different vegetation curving through roughly 110 degrees, sitting in the angle of a road T-junction. On the ground, this curve had already been rationalised into something mundane: the third edition of the Ordnance Survey six-inch map, published in 1946, records it simply as a curving field boundary. But the aerial image showed something the mapmakers either missed or disregarded, a small circular enclosure placed at the centre of the arc. The combination of the sweeping curve and the central circle is what led archaeologists to classify this tentatively as a designed landscape feature, meaning it may have been a deliberate ornamental arrangement rather than a purely functional boundary. Such features were sometimes created on landed estates as visual elements in the designed grounds around a house. Whether that is the case here remains genuinely uncertain; the classification is a careful guess, not a conclusion.

The site carries one further small confusion. Its official record was plotted slightly to the south of where the aerial evidence actually places it, just on the wrong side of Bunowen Bridge. Both the feature and its paperwork, it seems, are equally elusive.
