On that narrow shelf sits a circular stone structure, modest in every dimension yet quietly deliberate in its construction: three metres across, one metre high, and built from drystone laid in a corbelled technique, where courses of stone are stacked so that each layer projects slightly inward over the one below, gradually closing the space overhead without mortar or any binding agent. Walls nearly a metre thick suggest something intended to endure, or at least to resist the considerable weather that funnels through these mountain valleys.

Who built it, and when, is not recorded, but corbelled drystone structures of this kind are scattered across the Dingle Peninsula and have precedents reaching back into early medieval Ireland, when hermits, monks, and seasonal herders all had reason to construct simple, self-sufficient shelters in remote upland terrain. The location itself tells part of the story. Gleann Seanchoirp is not a place one arrives at casually, and the choice of this particular shelf on a steep slope implies either a need for seclusion or, just as likely, the pragmatic logic of a booley, a temporary summer dwelling used by those moving livestock to higher pastures. The site was documented as part of the Corca Dhuibhne archaeological survey published by J. Cuppage in 1986, a detailed inventory of the remarkable concentration of ancient remains across the Dingle Peninsula.
