The rath at Moyhullin, in County Clare, is one such site, a circular earthwork enclosure of the kind that once served as a defended farmstead during the early medieval period, roughly between the fifth and twelfth centuries. These structures typically consisted of one or more earthen banks and ditches enclosing a domestic space, and in some cases they were accompanied by souterrains, underground stone-lined passages that may have served for storage or refuge.

The townland name Moyhullin sits in the broader landscape of County Clare, a county unusually dense with early medieval settlement evidence. The word rath refers specifically to an earthwork ringfort, as distinct from a cashel, which is the stone-built equivalent more commonly found further west in the rocky terrain of the Burren. The presence of a rath in this part of Clare points to agricultural land capable of supporting the kind of settled farming community that would have constructed and maintained such an enclosure. Beyond its classification and location, the documentary record for this particular site remains sparse, and the details of its physical condition, dimensions, and any associated finds have not yet been made widely available.
