It sits in pasture roughly thirty metres south of the townland boundary with Ballygubba, and it would still be entirely unknown were it not for a dig that was actually looking for something else.

In 1989, archaeologists Christine Tarbett and Margaret Gowen were excavating what is recorded as House Site 2, one of at least two Neolithic house sites identified in the area, when they encountered the ring-ditch beneath it. A ring-ditch is essentially a circular or near-circular trench cut into the earth, often associated with burial or ceremonial activity, and the fact that this one was found cut directly into an earlier Neolithic house site points to a long and layered sequence of use and reuse of the same ground. The inner ditch had an external diameter of approximately five metres. It ranged from one to 1.2 metres in width and between 0.6 and 0.8 metres in depth, with a cross-section that shifted noticeably along its course, from a sharp V-shape in some places to a gentler U-shape in others. The soils found above it were almost indistinguishable from natural subsoil and contained no archaeological material; Tarbett and Gowen interpreted this layer as upcast, meaning the spoil thrown up from digging a separate outer ring ditch nearby.

The site is not accessible as a visitor destination in any formal sense. It lies in agricultural pasture and is not marked on Ordnance Survey Ireland historic mapping, which means there is no ground-level trace to seek out without prior knowledge of the excavation records. Anyone with a serious interest in the wider Tankardstown South complex would do better to approach it through the published excavation report, Tarbett and Gowen's 1990 account, and through the Archaeological Survey of Ireland's database entries, which list the related house sites and the ring-ditch separately. The value here is less in any physical visit than in understanding what the excavation revealed: a small, carefully shaped feature that survived beneath millennia of accumulated soil, invisible until the moment a trowel found it.
