These circular earthwork enclosures, known in Irish as raths, were the predominant form of rural settlement in early medieval Ireland, typically consisting of a raised bank and ditch enclosing a farmstead. Tens of thousands once existed across the island, and Clare has more than its share of them, scattered across the Burren limestone and the gentler farmland to the south and east.

The rath at Trusklieve belongs to this vast and only partially documented category of monument. Without more detailed records currently available, the specifics of its construction, its dimensions, or any associated finds remain out of reach for now. What can be said is that ringforts of this type were generally built between roughly the fifth and twelfth centuries, serving as the enclosed homesteads of farming families of varying social rank. The earthen banks provided a degree of protection for livestock and household, and in some cases souterrains, underground stone-lined passages, were dug beneath or adjacent to the enclosure, likely for storage or refuge. Whether any such features are associated with Trusklieve is not recorded here.
