The rath at Lissagarrymore, sitting on a gentle south-east-facing slope in the pastureland of Cloonmweelaun in north County Galway, is the opposite of that. Only a portion of its oval circuit survives as a legible earthwork, and even that is poorly preserved, making this one of those sites that rewards a careful eye rather than a casual glance.

A rath is an early medieval enclosure, typically from the first millennium AD, built with one or more earthen banks and ditches to define a farmstead or settlement. At Lissagarrymore, the oval measures roughly 66.5 metres east to west, and the remains that do survive consist of two banks with an intervening fosse, the term for the ditch cut between or outside the banks, running from the west-north-west around through the east and down to the south. Beyond that arc, no surface trace remains visible at all. A faint causewayed gap on the north-north-east side, where the earthwork appears to bridge across rather than cut clean, may mark the original entrance to the enclosure. A later field bank has since been built along the line of the outer bank from the west-north-west to the north, quietly borrowing the ancient earthwork as a convenient boundary and, in doing so, helping to obscure what was already a fragmentary outline. An associated feature catalogued separately under the Galway monuments record adds another layer to the site, though its nature is not elaborated here.
