It is a rath, the Irish term for a ringfort, and ringforts are among the most common archaeological monument types in Ireland, with tens of thousands recorded across the island. Most date from the early medieval period, roughly 500 to 1000 AD, and were typically the enclosed farmsteads of farming families, their circular banks and ditches defining both a working space and a social boundary. That they survive at all, so often, is partly because folklore long associated them with the fairy mounds of the otherworld, which made practical people reluctant to level them.

Lecarrow More itself is a small rural townland in Clare, and the presence of a rath there fits a pattern repeated across the county and the province of Munster more broadly. Clare's landscape holds a considerable density of these monuments, many of them tucked into field corners or straddling farm boundaries, their original earthen banks sometimes worn almost flat, sometimes still carrying a respectable height. The rath at Lecarrow More is one of these quiet survivals, noted and classified but, at present, not accompanied by detailed excavation records or documentary history that would fill in the specific names or events connected with it. What can be said with reasonable confidence is that it once marked the home ground of an early medieval household, a family whose identity is now entirely lost but whose construction effort has outlasted everything else about them.
