These enclosures, known in Irish as raths, were the farmsteads of early medieval Ireland, typically dating from around the fifth to the twelfth centuries. A raised bank of earth, sometimes reinforced with stone or a timber palisade, enclosed a family's dwelling, their animals, and their small world. Tens of thousands of them once dotted the Irish countryside, and a considerable number survive, worn down by centuries of farming, weather, and in many cases deliberate clearance.

The Tullassa example is one of Clare's quieter archaeological presences. The county itself is dense with early medieval settlement evidence, owing in part to the well-drained limestone landscapes of the Burren and its fringes, which made attractive ground for farming communities who needed defensible, workable land. Raths in this part of Ireland often appear on slight rises or at the edges of good agricultural ground, positioned to oversee both livestock and approach. Beyond its classification as a rath and its location in Tullassa, the specific history of this particular enclosure, its dimensions, condition, and any finds associated with it, remains undocumented in publicly available records at this time.
