The rath at Ballyvanna in County Clare is one such site, quietly occupying its place in the landscape without fanfare or, for the moment, much in the way of accessible documentation.

Ringforts, known in Irish as raths or liosanna depending on regional usage, were the standard enclosed farmsteads of early medieval Ireland, broadly from the fifth to the twelfth centuries. They typically consist of a roughly circular area enclosed by one or more earthen banks and ditches, within which a farming household would have kept their animals, stored food, and built their dwellings. Clare is particularly dense with surviving examples, owing in part to its mixture of limestone upland and lower-lying agricultural land, both of which suited the dispersed settlement patterns of the period. The Ballyvanna example belongs to this broader pattern, a rath rather than a cashel, meaning its enclosing boundary was built from earth and soil rather than the dry-stone walling more common in the rocky Burren country to the north.
