Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically consisting of a raised circular area enclosed by one or more banks and ditches. They served as farmsteads, the home and working space of a family or small community, and the ditch and bank arrangement, sometimes reinforced with a timber palisade, provided a degree of security for livestock as much as for people. Kerry has a remarkable density of them, and the fact that this one retains enough presence to be formally recorded speaks to the durability of earthwork construction.

The place-name Ballymacadam, combining the Irish baile, meaning townland or settlement, with a personal name, hints at a long association between a specific family or individual and this patch of ground, though the details of who farmed here, when the rath was built, and how the land changed hands over the centuries remain unrecorded in what is publicly available. What can be said is that the broader Kerry landscape was densely settled during the early medieval period, roughly the fifth to twelfth centuries, and that many of these earthwork enclosures were still in use, adapted, or built upon well into the Norman and later periods. The survival of a rath into the present often depended on whether the land was ever ploughed out, drained, or built over, and in the rough pasture and hill country of Kerry, many escaped that fate simply because intensive tillage agriculture never reached them.
