It was recorded in the Ordnance Survey Revision Name Books as a burial ground used for the interment of unbaptised children, and local tradition holds that adults were laid to rest here too. That dual identity, part cashel and part cillín, gives the site an quietly unsettling quality. A cashel is a type of ringfort defined by a drystone wall rather than an earthen bank, and a cillín is an informal, often unconsecrated burial ground of the kind used across Ireland for those who, for various reasons, could not be buried in sanctioned church ground.

What survives today is a poorly preserved, overgrown wall of drystone construction that forms a rough circle. It is most legible at the north-west arc, where the wall still stands around 0.3 metres high and measures about 1.6 metres across. Loose stone is scattered across the interior, and in the south-east quadrant a series of upright grave-markers are arranged in rough north-south rows, averaging about half a metre in height. The site was documented by Ó Cíobháín in 1984 and later included in the archaeological survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996. The landscape context is worth noting: the southern end of a small Kerry island, with an unobstructed sightline down a tidal bay, is an unusual setting for a monument that probably began as a defended or enclosed farmstead before acquiring its more solemn later use.
