These circular enclosures, known in Irish as raths, were the farmsteads of early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. A raised bank of earth, sometimes reinforced with a stone wall and surrounded by a ditch, defined the boundary of a family's domestic space, sheltering a house, outbuildings, and livestock from the world outside. Tens of thousands of them once existed across Ireland; several thousand survive in some form today, though many have been levelled by centuries of agriculture.

Coolreagh More is a small rural townland in Clare, a county whose limestone karst interior and Atlantic-facing coast have preserved an unusually dense concentration of early and prehistoric remains. The rath here is one of countless such monuments scattered across the county, each one a trace of the patchwork of small farmsteads and family territories that made up Gaelic Ireland before and during the early Christian period. Without more detailed recorded information currently available for this specific site, the particulars of its condition, dimensions, or any associated finds remain undocumented in accessible form.
