Enclosures of this kind turn up across the Irish landscape in considerable numbers, ranging from the remains of early medieval ringforts, which were circular earthen or stone-walled farmsteads occupied roughly between the fifth and twelfth centuries, to later field boundaries and ecclesiastical enclosures whose origins can be harder to pin down. Kerry, with its dense archaeological record and varied terrain, has more than its share. Knockawaddra itself is a small townland, and like many such places its name carries meaning folded inside it, though without further documentation the enclosure's age, construction, and purpose remain open questions.
