A low earthen bank traces the perimeter of a subrectangular hut site, roughly 18 metres north to south and just under 6 metres east to west, sitting in the southern half of the enclosure. It is unassuming on the surface, easy to overlook, but the dimensions and the surviving bank are enough to confirm a domestic structure, a building that once stood within the protected space of a rath.

A rath, also known as a ringfort, is a roughly circular enclosure defined by banks and ditches, most commonly associated with farming households of the early medieval period in Ireland, broadly from around the fifth to the twelfth centuries. They were the ordinary dwellings of their time, and thousands survive across the country in varying states of preservation. What makes this example at Corraun quietly interesting is the internal arrangement. The southern hut site is not alone; a second hut site occupies the northern half of the same enclosure. Two structures sharing a single rath suggests a household with some complexity, perhaps a main dwelling alongside a working space, a store, or accommodation for dependants. The site was recorded as part of the Archaeological Survey of Ballinrobe and District, which catalogued it among the monuments of the surrounding region.
