Not a doorway, not a gap, not a fosse, which is the ditch that typically rings a defensive earthwork. Just a continuous wall, roughly forty metres across from east to west and thirty from north to south, enclosing a space that was clearly worked hard and then sealed. That absence is the first thing worth dwelling on.

The wall itself is carefully made. At a metre and a half wide and standing higher on its outer face than its inner one, it reads less like a boundary thrown up in a hurry and more like something built to last and to impress. The outer face is capped with alternating long and short stones laid in a regular pattern, a technique that speaks to deliberate craftsmanship rather than agricultural improvisation. On the northern, upslope side, a secondary inner wall was added at some point, most likely to buttress the original construction against the pressure of the hillside above. Inside the enclosure, the ground has been thoroughly cleared. The large boulders that could not be removed were instead incorporated as foundations for clearance cairns, carefully stacked and faced piles of stone that represent a considerable investment of labour. The enclosure sits within a wider field system built to the same massive standard, suggesting this was not an isolated structure but part of an organised and substantial landscape.

What the enclosure was actually for remains an open question. The combination of a high-quality boundary wall, meticulous internal clearance, and the complete absence of any entrance feature makes it difficult to read as a simple paddock, though it is classified within a field system that functioned as one. Whether animals were ever kept here, and if so how they got in and out, is not answered by anything the structure currently shows.
