The hollow, roughly ten metres long and five metres wide, is what remains after centuries of stone-robbing stripped away most of what had been built there. What you are looking at is not just a ruined structure but an absence, the negative shape left by a building that was gradually dismantled and carted away.

The site sits just inside the entrance of a univallate rath, one of four such enclosures clustered on this part of Corrin Hill. A univallate rath is a type of early medieval farmstead enclosure defined by a single earthen or stone bank, common across Ireland between roughly the sixth and tenth centuries. Here, positioned directly inside the south-west entrance gap, were one or possibly two small stone huts. At the eastern end of the hollow, a few stones from the inner face of one hut survive in place. The hut was modest, somewhere between three and four metres in diameter, and its entrance, oriented to the north-east, is still partly lined with a single course of masonry. Whether the western end of the disturbed area held a second hut or an annex is not clear; the ground has been too thoroughly robbed to say with confidence. Two boulders set upright on edge, running between the western end of the hollow and the gap in the ringfort bank, may once have formed part of a formal entrance way into the huts. Described by J. Cuppage in the 1986 Dingle Peninsula Archaeological Survey, the site captures in miniature the difficulty of reading early medieval domestic space when the building materials have long since been recycled into later walls and field boundaries elsewhere on the hillside.
