It is a modest feature by any measure, the kind of thing that could be walked past without a second glance, yet what was found inside it tells a quietly remarkable story about life on this remote island site.

The cistern was rock-cut on the southern side of the round house, and crucially it predates the annulus, the circular enclosing wall that was later built around the structure. This sequence matters: it places the cistern among the earliest phases of activity on the site. When archaeologists excavated its fill, they recovered over one hundred quartz pebbles along with fragments of hide. Quartz was widely regarded in early medieval Ireland as having ritual or protective significance, and its concentrated presence here, alongside organic hide material, suggests the cistern may have been deliberately closed or decommissioned in a manner that was anything but casual. Whether it originally functioned as a water store, a container for soaking hides, or served some other practical purpose, the circumstances of its filling raise more questions than they answer. The survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan, published by Cork University Press in 1996, remains the primary source for what is known about the site.
