It is, in fact, a cillín, a type of burial ground historically reserved for unbaptised infants and very young children who, under Catholic doctrine, could not be interred in consecrated ground. Such places are found across Ireland, often unmarked and easily overlooked, and this one carries the older place-name 'Killouragh'. The interior shows three distinct grave mounds lying just south of the road, each roughly 1.8 metres long and 0.4 metres high, and five oval depressions set just inside a low scarp along the southern edge, the kind of subtle hollowing that long-settled ground eventually makes around buried remains.

By the 1940s the site was still in active use, and members of the County Kerry Field Club noted that some of the mounds were strewn with white pebbles, a funerary custom that quietly persisted here even as formal churchyard burial became the norm elsewhere. The burial ground is closely associated with the ruins of a possible early church nearby, and the whole cluster of sites formed part of a 'rounds' ritual, a devotional practice in which participants would visit a series of sacred spots in a fixed order, moving clockwise and typically reciting prayers at each station. These rounds at Kilclogherane were traditionally performed either after dark or before dawn on the 1st of May and the 1st of August, the old Gaelic seasonal festivals of Bealtaine and Lughnasa. The route took in two holy wells, one to the east and one to the west of the church ruins, with the eastern well known as Tobermurry and lying about forty metres from the burial ground. During the Penal Laws period, when Catholic worship was suppressed and priests faced severe legal penalties, this was also recorded as a place where Mass was celebrated in the open air, using the concealment of darkness and the remoteness of the landscape rather than the shelter of a building.
