These enclosures, known in Irish as raths, were the farmsteads of early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. A bank of earth, sometimes reinforced with a ditch, enclosed a family's dwelling and offered a degree of protection for livestock. Tens of thousands of them once existed across the island; a remarkable number survive, often as slight rises in a field that a passing eye might mistake for a natural feature.

Clare is particularly well supplied with them, its landscape peppered with the circular marks of former settlement that speak to a dense agricultural past. Furroor itself is a small rural townland, and the presence of a rath there fits a broader pattern across the county, where early Christian-era farmers chose elevated or well-drained ground for their enclosures, positioning them to oversee their fields and pasture. The word "rath" is one of several terms used for these structures, alongside "lios" and "dún", each carrying slightly different connotations in the historical record, though the physical remains are often indistinguishable from one another on the ground.

Beyond its classification and location, the specific details of this particular enclosure, its dimensions, current condition, and any finds or features associated with it, remain to be fully documented in the public record. What can be said is that it occupies a place in a landscape shaped as much by prehistoric and early medieval activity as by anything that came after, and that Clare's ringforts, however unremarked individually, collectively form one of the more tangible connections to the lives of ordinary farming families in early Ireland.
