The one at Bolooghra, in County Clare, is among them. A rath, as this type of earthwork enclosure is known in Irish, typically consists of one or more roughly circular banks and ditches, thrown up during the early medieval period, between roughly the fifth and twelfth centuries, to enclose a farmstead or the dwelling of a local chieftain.

Clare is particularly dense with such monuments, owing to the county's long and layered pattern of rural settlement. The Burren to the north is famous for its concentration of prehistoric and early medieval sites, but the broader county holds ringforts across its lowlands and drumlins as well, many of them sitting in quiet townlands whose names preserve older Irish forms. Bolooghra itself is one of those townland names that has come down through centuries of anglicisation, carrying something of an earlier world inside its syllables, even if the documentary record attached to this particular site remains thin.

Beyond its existence as a classified monument, the specific history of this ringfort, its dimensions, condition, and any associated finds or features, is not currently available in detail. What can be said is that it belongs to a category of site that once formed the basic unit of rural life in early medieval Ireland, not a fortress in the military sense but an enclosed homestead, a place where a family's cattle were kept safe at night and where daily life turned around the rhythms of farming, craft, and obligation to a local lord.
