Ringforts, known in Irish as raths, were the standard form of rural settlement across early medieval Ireland, roughly from the fifth to the twelfth centuries. A typical example consists of one or more banks of earth and accompanying ditches enclosing a roughly circular area, within which a farming family would have lived, kept livestock, and stored food. They were not primarily military fortifications, despite the name, but homesteads, their banks offering a degree of protection against animal theft and marking out a household's claim on the land.

Kerry's particular density of ringforts reflects both the county's fertile pockets of agricultural land and the relative continuity of rural settlement patterns there across many centuries. The townland name Ballydwyer, from the Irish Baile Uí Dhuibhir, suggests an association with the Ó Duibhir family, a sept whose presence is recorded across Munster. Beyond that connection, the specific history of this enclosure, its construction date, any finds recovered nearby, and the precise condition of its earthworks, remains to be fully documented in the public record.
