A cashel is a ringfort built from dry-stone walling rather than earthen banks, a form of enclosed farmstead typical of early medieval Ireland, roughly between the fifth and twelfth centuries. Thousands of these survive across the country, particularly in the west where stone was more abundant than good timber or deep soil. This one, however, has so far escaped detailed public documentation.

Ringforts of this kind were not defensive structures in any military sense, though the enclosing wall gave some protection against wolves and cattle raiders. They were, most typically, the homesteads of farming families of moderate status, the wall defining a domestic space that might contain a house, outbuildings, and space for animals overnight. Clare is particularly rich in such monuments, and the concentration of cashels across its limestone landscape reflects both the geology and the density of early medieval settlement in the region. Creevagh Beg, like many small townlands in the west of Ireland, carries its history quietly in the ground rather than in any written record that has yet been made widely accessible.
