One of the site's several stone remains, designated Structure 6, began life as a clochán, a circular dry-stone beehive hut of the kind found across the Dingle Peninsula, typically associated with early medieval monastic or farming communities. At some later point, an irregular corbelled chamber was constructed within its southern half, reusing the original wall as part of its own fabric. The entrance passage of the newer chamber was threaded through the same south-east facing opening the clochán had used, so that the old doorway became the mouth of something quite different.

The detail of how the two phases sit together is quietly remarkable. The original clochán measured 4.6 metres in diameter internally, with a corbelled wall surviving to roughly 0.65 metres in height, its stonework described as neatly constructed. The later chamber inserted into it is considerably smaller, just 2.65 metres by 1.7 metres, and its corbelled roof closes at a height of 2.75 metres above the floor. The entrance passage running into it is 2.7 metres long and around 0.85 metres wide, narrow enough to require some ducking at the innermost lintel, which is set only 1.6 metres above the floor, though the outer portion of the passage is a more comfortable 2.1 metres high. The upright jamb stones near the inner end of the passage align with the inner face of the earlier clochán, suggesting they mark where the original entrance once ended. To the north, the passage wall runs up to, but was never bonded into, an adjacent structure. The two buildings touch without being joined, a detail that speaks to separate campaigns of construction by people who were working around, rather than demolishing, what came before them. Archaeological survey work by J. Cuppage, published in 1986 as part of the Dingle Peninsula survey, recorded the structure in its present layered condition within the wider cashel enclosure.
