Enclosures of this kind, broadly defined as any area bounded by an earthen bank, a stone wall, or a combination of both, are among the most common yet most quietly ambiguous features of the Irish archaeological record. They might date from the early medieval period, when ringforts served as farmsteads, or from much earlier. Without further detail, the site belongs to that particular category of place that is known to exist, known to matter, and not yet fully explained.

Farrannabrack is a Kerry townland, and Kerry as a whole holds an unusually dense concentration of such earthwork features, a reflection of both the county's long history of settlement and the relative survival of field monuments in areas that escaped intensive later cultivation. The enclosure at Farrannabrack has been formally recorded as an archaeological monument, which means it carries legal protection under Irish heritage legislation, but the specific details of its form, dimensions, and date remain, for now, unavailable in any accessible public format.
