The enclosure measures roughly fourteen metres across in both directions, making it almost exactly circular, and a single entrance, just under three metres wide, opens to the south. That southward orientation is common in early Irish enclosures and is generally thought to relate to light, shelter, or both.

Enclosures of this kind are among the more enigmatic features of the Irish archaeological landscape. The term covers a broad range of stone-walled circular or oval spaces whose original function is often unclear without excavation. Some served as farmsteads, some as funerary or ritual spaces, and others as enclosures for livestock. The roughly fourteen-metre diameter here is on the smaller end of the scale, which tends to suggest a domestic or agricultural use rather than a large ceremonial one, though without further investigation that remains speculation. What is clear is that the wall survives, the entrance is intact, and the ferns have made themselves thoroughly at home inside.
