A cashel is a type of ringfort built from dry-stone walling rather than earthen banks and ditches, and the name Caheravoley itself carries traces of this heritage, most likely derived from the Irish cathair, meaning a stone fort. Ringforts of this kind were typically built during the early medieval period, roughly between the fifth and twelfth centuries, and served as the enclosed farmsteads of farming families, protecting livestock and living quarters within a defined boundary.

The townland name alone suggests this was once a landscape shaped by such enclosures, possibly clustered or prominent enough to give the place its identity. Cashels are found throughout the west of Ireland, where surface stone was plentiful and earthen construction less practical, and Galway contains a considerable number of surviving examples. Many have been absorbed into field boundaries or damaged by later agricultural activity, while others remain largely intact, their walls still readable as coherent structures in the terrain. Without more specific documentation available, the precise condition, dimensions, or ownership history of this particular site remain unclear, but its classification as a recorded monument confirms it has been identified as a surviving archaeological feature worthy of protection under Irish heritage legislation.
