The rath at Leamcon, in County Galway, offers rather less. What survives is partial, worn down, and on its eastern side has vanished entirely into the grass of a sloping field.

A rath is a type of ringfort, a circular earthwork enclosure typically used as a defended farmstead during the early medieval period in Ireland, roughly the fifth to twelfth centuries. The defining features are a raised bank and an external fosse, the fosse being the ditch dug to provide the material for that bank. At Leamcon, the enclosure measures around twenty metres in diameter, modest even by the standards of a site type that varies considerably in scale. The bank-and-fosse circuit is still discernible in places, but the fosse has silted and been colonised by briars in sections, and the eastern arc of the bank has left no visible trace at all. An east-facing slope in open grassland is not the most forgiving environment for earthwork survival, exposed as it is to erosion and the long pressure of agricultural use.
