What makes this particular structure quietly odd is not its age or its modest dimensions, but the confusion it has generated on maps and in scholarship for well over a century. Nineteenth-century Ordnance Survey plans labelled it an "Ancient wall with cave", a designation that persisted into the 1920 edition of the six-inch map. As recently as 1977, it appeared on a specialist map as a souterrain, which is an underground stone-lined passage typically associated with early medieval settlement and used for storage or refuge. In fact, the feature in question is a small stone-lined hollow inside the hut's eastern interior, roughly a metre square and less than a metre deep, with a stone set into its base. It is almost certainly a well, not a cave or an underground passage.

The misidentification has a named advocate. T. J. Westropp, the prolific Clare antiquarian, described it as a souterrain in 1897, and the label stuck long enough to find its way onto Robinson's 1977 map, decades after his original note. The hut itself is defined by a stone wall between one and one and a half metres wide, with large upright stones forming its inner face, some reaching 1.2 metres in length. The interior measures approximately 6.6 metres north to south and 6 metres east to west. A gap roughly two metres wide in the south-eastern wall appears to be the result of non-recent damage rather than an original entrance. The structure sits within a dense cluster of early remains: a cashel called Cahercutteen, which is a type of stone-walled ringfort, lies about 37 metres to the north-north-east, and the hut is thought to have been associated with it. A cairn site lies some 20 metres to the north-east, another enclosure about 94 metres to the south, and a second cashel, Caherwalsh, around 160 metres to the south-south-east. Taken together, the immediate area preserves a layered picture of early settlement activity, with this small, misnamed hut quietly at its centre.
