Where the more familiar rath was thrown up from banked soil and ditch, the cashel belongs to a tradition of enclosure in stone, common across the rocky western seaboard where the land itself supplied the building material in abundance. These roughly circular enclosures served early medieval communities, broadly from around the fifth to the twelfth century, as farmstead boundaries, places of habitation, and in some cases as sites of local status. They are found across Clare in considerable numbers, tucked into field systems and hillsides, easy to overlook if you do not already know what to look for.

The cashel at Cappagh More is one of those monuments whose particular history remains, for now, largely unrecorded in any publicly accessible form. What can be said with confidence is that it belongs to a broader pattern of early medieval settlement across the Clare landscape, a county whose geology, with its limestone pavements and ready stone, made the cashel form especially practical. Cappagh More as a place-name suggests a townland of some size, the Irish word "cappagh" relating to a plot or tillage area, and "more" simply meaning large. The presence of a cashel here fits the wider picture of dispersed rural settlement that characterised this part of Munster throughout the early medieval period, when individual farming households enclosed their homesteads against livestock straying and, perhaps, as a mark of the household's standing in the community.
