A cashel is a stone-walled enclosure, the western Irish equivalent of a ringfort, its boundary formed not by an earthen bank but by a drystone wall. Here that wall, preserved to about two metres in height and consisting of a rubble core faced on both sides with drystone masonry, encloses what amounts to a small settlement compressed into a tight space, with at least six distinct internal structures still identifiable.

The complexity of the interior is what sets this site apart from more straightforward enclosures. Corbelled clochans, small dry-stone beehive huts roofed by courses of overlapping stone rather than timber or thatch, occupy much of the interior, some opening directly onto one another, some later insertions cannibalising the walls of earlier buildings. When the antiquarian George Victor Du Noyer recorded the site in 1858, one small hut just inside the entrance still retained its corbelled roof intact. By the time R. A. S. Macalister visited in 1899, that entrance had been closed and a gap broken through the cashel wall elsewhere. A restoration programme carried out by the Office of Public Works in 1984 cleared collapse that had long obscured the inner face of the western wall, revealing two short terrace stretches and bringing sections of the original fabric back into view. Tucked within the thickness of the eastern cashel wall is an L-shaped passage, less than a metre wide and less than a metre high, that extends nearly five metres northward before its original interior entrance was blocked. Loose in the interior lie a fragment of a rotary quernstone and a fragment of a millstone, the quiet residue of everyday grain-processing. Macalister also recorded an inscribed stone reportedly found within one of the structures; it bore a circle, an equal-armed cross, and a cross-in-circle, though he doubted its authenticity, suspecting it might be of recent manufacture. That stone is now held at the National Museum of Ireland.

The site sits in a landscape on the Dingle Peninsula already dense with early medieval remains, and approaching it from the southern slopes of Mount Eagle gives a clear sense of why the position was chosen, with broad views out over the bay below. The entrance passage on the south-east, nearly three metres long and lined with opposed upright slabs at its midpoint, requires some ducking to pass through, which gives an immediate sense of the scale at which these structures were built and used.
