The wall in question forms an oval enclosure, roughly twelve metres east to west and five metres north to south, built in the drystone manner, meaning without mortar, relying instead on the careful fitting of stone against stone. It has collapsed and sunk, but it has not disappeared. Moss covers much of what remains, and the upper courses have long since tumbled, yet the lower courses of large stones still protrude just above the surrounding boggy ground, tracing the outline of the original structure clearly enough to read.

Drystone enclosures of this kind are found across upland Kerry, often associated with early agricultural or pastoral activity, and the presence of a hut site approximately thirty metres to the east suggests this was once a small working landscape rather than an isolated feature. Someone, at some point, built a place to live alongside a defined area of ground, perhaps for sheltering animals, storing materials, or marking out a cultivated plot on the edge of rough hill pasture. The terrace setting on the northern slope of Knockmoyle would have offered a degree of shelter and a relatively level patch of ground in otherwise demanding terrain. Without excavation, precise dating remains out of reach, but the combination of enclosure and adjacent hut is a pattern familiar from early medieval and later settlement in the Irish uplands.
