These enclosures, known in Irish as raths, were the farmsteads of early medieval Ireland, typically defined by one or more earthen banks and ditches thrown up to protect a household, its livestock, and its stores. Tens of thousands of them once dotted the island, and a significant number survive, worn down but legible, in fields that have been ploughed and grazed around them for centuries.

The Tullaroe example belongs to that broad and still only partially documented category of ringforts scattered across the Clare landscape. Clare itself sits on a limestone plateau that made it both fertile enough to farm and hard enough to preserve earthworks that softer ground elsewhere might have swallowed. The rath form was in common use from roughly the sixth to the twelfth centuries, though many enclosures were occupied, adapted, or simply left alone well beyond that span. What a particular ringfort looked like in use, who held it, and what became of its occupants are questions that tend to go unanswered unless excavation or documentary evidence intervenes.
