Rather than forming a complete circuit of walling, whoever built this structure simply used the natural outcrop as one side, leaving only the curved portion to be built by hand. The result is a D-shaped enclosure, roughly 11.5 metres by 10 metres internally, with its straight north-eastern edge formed entirely by the living stone.

The built sections are modest but deliberate. Large stones define the perimeter, which stands around half a metre high and about a metre wide, with some sections of double-faced drystone walling surviving at the north-west, a construction method in which two parallel lines of stone are laid with the faces outward, lending the wall more stability and bulk. Inside, the ground slopes sharply down to the south-west and is scattered with spreads of fist-sized stones, most likely the accumulated result of field clearance over time, stone by stone moved out of the way of whatever activity the enclosure was meant to support. The Ordnance Survey 25-inch map, which was produced in the late nineteenth century and captured land use at a level of detail rarely matched since, labels this structure simply as a sheepfold, a practical designation that sits a little awkwardly with the architectural care evident in the drystone work. It is possible the enclosure was already old when the surveyors came through, repurposed or reinterpreted across generations, its original function quietly absorbed into the ordinary rhythms of farming life.
