The rath at Carrowmoneen offers no such convenience. Sitting in level grassland in north County Galway, this early medieval enclosure has been so thoroughly worn down that the northern arc of its defining bank, from the north-north-west around to the north-north-east, has left no visible trace whatsoever on the surface. What remains is a subcircular earthwork measuring roughly 29 metres north to south and 25.5 metres east to west, and even that survives only partially.

A rath, sometimes called a ringfort, was typically a farmstead of the early medieval period, enclosed by one or more earthen banks and ditches. These were domestic rather than military structures, built to protect a family and its livestock rather than to withstand a siege. Thousands survive across Ireland in varying states of repair, but Carrowmoneen represents the quieter end of that spectrum. The enclosure is described as poorly preserved, and the missing northern section suggests centuries of agricultural activity have gradually smoothed the bank back into the surrounding field.
