A hollow roughly 6.7 metres long, 4 metres wide, and half a metre deep marks the roof-fall of a souterrain, an underground stone-lined passage or chamber system typically built during the early medieval period, often as a place of refuge, food storage, or concealment. The depression sits at the centre of a ringfort, the circular earthen enclosure that once defined a farmstead, and the collapsed ground extends westward from the centre toward the enclosing bank, tracing something of the original layout underground.

Two stone lintels, the flat capstones that would have roofed the chambers, are exposed at the eastern end of the hollow. A third sits partially visible in a nearby animal burrow, dislodged from whatever position it once held. The spoil scattered around the site points to digging at some point in modern times, though the nature and purpose of that activity is not recorded. What remains is a structure in a state of quiet ruin, its roofline gone and its chambers open to the sky, the lintels serving less as a roof now and more as an indication of what the original construction looked like before the ground gave way.
