No earthwork, no hollow, no scatter of stone. The only evidence that anything was ever there comes from an Ordnance Survey map drawn in 1838, which recorded a circular form in what is today open pasture, with marsh lying to the east.

What the mapmakers recorded may well have been a ringfort, the most common type of early medieval settlement monument in Ireland. Ringforts, typically built between roughly 500 and 1000 AD, were enclosed farmsteads, their circular banks and ditches defining a domestic space for a family and their livestock rather than a military fortification. At Clooncorraun, whatever once stood here had already been levelled by the time any systematic archaeological attention came to the area. D. Lavelle's survey of the Ballinrobe district, published in 1994 by the Lough Mask and Lough Carra Tourist Development Association, noted its probable character and its complete disappearance, classifying it simply as a levelled enclosure of possible ringfort type.

What makes this site quietly striking is precisely its absence. The 1838 OS mapping captured it at some point before its final erasure, preserving at least the memory of a circle on a ridge slope. That circle is now gone, absorbed back into the pasture, and nothing visible remains for a visitor to find.
