The rath at Ballyfaudeen in County Clare is a quiet exception. It does not appear on the OS 6-inch maps at all, and was only formally catalogued as an enclosure in the Record of Monuments and Places in 1996. It sits in low-lying pasture among gently rolling hills, overlooked by rising ground to the east, with open views stretching southward, the kind of position that would have made practical sense to whoever chose it, yet the site has slipped through the documentary record with unusual ease.

What survives is a subcircular platform, roughly 25 metres north to south and 27 metres east to west, raised between 0.3 and 1.4 metres above the surrounding ground. A ringfort or rath of this type would typically have been a farmstead enclosure during the early medieval period, perhaps between the fifth and twelfth centuries, defined by an earthen bank and an outer ditch. Here, though, there is no trace of an intervening bank between the platform and its enclosing fosse, the flat-based ditch that runs around it. That fosse varies considerably in depth, reaching 1.8 metres along the eastern side where the ground naturally rises and amplifies the effect. The western side of the fosse has an additional peculiarity: a dry stream bed, now readable only as a rush-filled depression running roughly north to south for about 250 metres, feeds into the fosse at the north, and the fosse's western edge appears originally to have been formed by the stream itself. Water, in other words, was not just nearby but structurally incorporated into the enclosure. The interior is level and shows no visible features above ground, and a later field boundary cuts across the southeastern edge of the monument, one of those small rural intrusions that quietly records centuries of subsequent land use.
