At Carrowmore in County Galway, a circular rath, a type of enclosed farmstead typically dating from the early medieval period, roughly the fifth to twelfth centuries, has been worn down to the point where much of its original form must be inferred rather than read. A rath generally consists of one or more earthen banks with a ditch, enclosing a domestic or agricultural space, and this one would once have followed that familiar pattern. What remains now is fragmentary: two banks with an intervening fosse, the ditch between them, visible only from the west-southwest through the north and around to the east. To the southeast, even that has collapsed into a degraded scarp, a low slumped edge that is all the monument can still manage in that direction.

The rath measures approximately forty metres in diameter and sits around two hundred metres east of a second ringfort, suggesting this was once a landscape with more than one enclosed settlement in relatively close proximity, a pattern not unusual in early medieval Ireland where family groups and their dependants might each occupy their own enclosure within the same territory. The site has been further compromised by a field wall that cuts directly through it at the east and west-southwest, a reminder of how later agricultural reorganisation quietly dismantled earlier archaeology across much of the country. The result is a monument that has been divided, eroded, and reduced, its once-coherent circuit now broken into disconnected arcs.
