The word "possible" is doing considerable work here, and that uncertainty is itself part of what makes the site interesting. Not every archaeological feature announces itself clearly, and a souterrain that has not been fully confirmed sits in a particular category, present enough to be recorded, elusive enough to resist easy classification.

The site at Cill Na Gcolmán is noted in the archaeological survey of South Kerry compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996. Cill Na Gcolmán, the name suggesting an early ecclesiastical foundation associated with Saint Colmán, would be a plausible context for a souterrain. Such structures are frequently found in association with early Christian settlements across Ireland, where they served practical purposes beneath the ground while the religious and domestic life of a community continued above. The western aspect of the site, with its open view across flat ground, is the kind of detail that quietly locates a place in real geography without making it easier to find.
