What makes it quietly puzzling is the gap between what it appeared to be on paper and what it turned out to be in person. Ordnance Survey maps from both 1840 and 1916 mark it with hachures, the conventional cartographic notation used to indicate an earthwork or enclosed feature of some age and significance. For well over a century, that marking sat on the map unchallenged.

When the site was physically inspected in 1997, the picture changed considerably. The enclosure is subrectangular in shape, roughly 25 metres north to south and 20 metres east to west, and defined by a drystone wall, a type of wall built without mortar, with stones set upright along its course. The wall reaches no more than a metre in height and about 0.8 metres in width at its broadest. Crucially, it was found to be of modern construction, built directly on the sod with no earlier stone facing or spread beneath it, and no archaeological material predating the walls themselves. Some sections have already begun to collapse, with stones spilling outward. The ravine surrounding it, around 20 metres wide and 5 metres deep, gives the site a quality of natural isolation that may well have contributed to its long misreading as something older and more deliberate than it actually is.

The site sits within a valley that is heavily overgrown, and the combination of scrub cover and the encircling ravine means it is not straightforward to approach. Visitors in summer will find the hazel growth at its densest, which obscures both the wall itself and any sense of the enclosure's shape from ground level.
