The example at Knockmore in County Clare is a rath, the term used for a ringfort constructed primarily from earthen banks rather than stone, and it sits within a landscape that has been farmed and settled since the early medieval period, roughly between the fifth and twelfth centuries, when these circular enclosures served as farmsteads for free-farming families.

A rath typically consists of one or more concentric earthen embankments, sometimes accompanied by an outer ditch, enclosing a roughly circular area where a family would have kept their home, their animals, and their stores. The number of banks was often a rough indicator of the owner's status, with single-banked examples being the most common and triple-ringed ones suggesting considerable wealth or importance. The Knockmore example belongs to this widespread but deeply significant tradition of early Irish rural settlement, and its presence on the landscape is a reminder that the fields around it have been shaped by human activity for well over a thousand years. County Clare is particularly dense with such monuments, the region's mix of limestone plains and sheltered ground having made it attractive to early farming communities.
