On a south-west-facing grassland slope in County Galway, the remains of a circular rath roughly thirty metres in diameter have been so thoroughly reduced by quarrying that the northern and south-eastern portions of its enclosing elements have vanished entirely from the surface. A rath is a type of ringfort, an enclosed farmstead of early medieval Ireland typically defined by one or more earthen banks and ditches, used as a defended homestead by a family of some local standing. Here, only a scarp, the remnant of an intervening fosse or ditch, and a fragment of outer bank hint at what the original circuit once looked like. A field wall has been driven through the monument at the north-west and north-east, compounding the damage.

What makes this site quietly worth noting is not what remains but what the landscape around it reveals. Approximately thirty metres to the east-south-east, a second ringfort survives, a proximity that suggests this small corner of north Galway once held a cluster of related early medieval settlement activity. Pairs or loose groupings of ringforts are not unusual in Ireland; they may reflect extended family units farming adjacent plots, or successive generations reusing familiar ground. At Tonlegee, though, the quarrying that consumed much of the rath has made it difficult to read the two sites in relation to each other with any confidence, and the monument is now, as surveys have noted, very poorly preserved.
