Cillíní were unconsecrated burial grounds where unbaptised infants, and sometimes others excluded from Catholic churchyard burial, were laid to rest, often at ancient or liminal sites. This one does not appear on Ordnance Survey maps at all, existing instead in local memory and in the kind of fragmentary scholarly record that accumulates around places too old and too unofficial to be easily categorised.

The site was recorded by a researcher named Henry in 1957, who described it using the term 'cellurach', an Irish word referring to a burial ground associated with an early ecclesiastical enclosure. That description suggests the place may have roots stretching back to the early Christian period in Ireland, when small monastic communities and hermitage sites were scattered across the Kerry landscape, often leaving little behind but a name, an enclosure, and a local reputation for sanctity. Henry noted features within the site, though by the time scholars from A. O'Sullivan and J. Sheehan's survey of the Iveragh Peninsula came to examine it in the 1990s, those features had become very difficult to read on the ground. The enclosure is heavily overgrown, and a considerable amount of field clearance debris, stones and spoil gathered from surrounding farmland and dumped here over the years, has further obscured whatever structural evidence once existed. The site sits on the same slope as a related monument approximately 320 metres to the south-west, suggesting this part of the hillside once held some wider early medieval significance.
