It has since been levelled entirely, so what survives now is largely a matter of record rather than remains. What makes the site quietly interesting is not the hut itself but what surrounded it: a cross-inscribed boulder lying about 30 metres to the south-east, and a souterrain whose opening was located roughly 8 metres to the north-west. A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement in Ireland, used variously for storage, refuge, or both. Local knowledge held that this one had two separate passages, though no formal excavation appears to have confirmed that detail.

The site came to wider notice through a reference by O'Connell in 1939, who described what was probably the same collapsed structure as a "chambered cairn", a term that usually implies prehistoric funerary use. Whether the mound was originally a burial monument later reused or built over during the early medieval period, or whether O'Connell was simply working from an ambiguous heap of stones, is difficult to say at this remove. The cluster of features, a marked boulder, an underground passage, and a collapsed structure of uncertain age and function, suggests a place that accumulated significance over a long stretch of time, each addition made in the context of what was already there. The Iveragh Peninsula, on which Ballydarrig sits, has a high density of early medieval and prehistoric remains, and this kind of layered, overlapping archaeology is not unusual for the area, even if the individual sites rarely receive much attention.
