D-shaped in plan, partially dug into the slope, and divided internally into two unequal compartments, it sits just three metres east of an older field boundary. No entrance is visible, which immediately marks it out as something that resists easy interpretation. Was it a shelter, a store, a fold for animals? The absence of a doorway is the kind of detail that quietly unsettles a tidy explanation.

The structure is modest in its dimensions, roughly five metres on its longer axis and three metres across, with dry-stone walls, a building technique that uses no mortar, relying instead on the careful fitting of stones against one another. Those walls survive to a maximum height of only 0.4 metres and are about 0.6 metres wide, enough to suggest something deliberately and fairly solidly built, even if little of it now projects above the ground surface. The internal division is particularly curious. Splitting the interior into two unequal parts implies some specific functional purpose, though what that purpose was remains unclear. Hut sites of this kind are found across the Irish uplands and are notoriously difficult to date without excavation; they could belong to any period from the early medieval to the post-medieval, and many were associated with seasonal grazing activity known as booleying, the practice of moving livestock to higher pastures in summer months.
