The structure is a cashel, the stone-built equivalent of the earthen ringfort, a type of enclosed farmstead or high-status residence common across early medieval Ireland. What survives here is modest by any measure: a collapsed drystone wall now barely distinguishable from a rubble scatter, with only the eastern stretch retaining any clear sense of how it was originally built.

The antiquarian Thomas Johnson Westropp, writing in 1915, recorded what is almost certainly this same structure, describing it as a small house ring with a coarsely built wall, then standing barely a yard high, on a knoll of crag. A century later, the picture is considerably reduced. The cashel's interior measures roughly 21.5 metres north to south and 19.1 metres across, making it a modestly sized but recognisable example of the type. The wall itself, where it survives in any coherent form, sits between 0.4 and 0.8 metres wide in its present collapsed state, though traces of both inner and outer facing stones at the east reveal an original wall width of around 1.6 metres, solid enough to have formed a real boundary. The site sits within a larger multiperiod field system, suggesting that farming activity in this part of the Burren extended across many centuries, with the cashel forming just one layer in a long sequence of land use on the same plateau.
