It has a designation but, for now, little else that can be said with certainty about its age, its purpose, or the hands that raised it.

Mounds of this kind in the Irish countryside belong to a broad and varied family of earthworks. Some are burial mounds, raised over the dead during the Bronze Age or earlier. Others are the eroded remnants of mottes, the raised platforms on which Norman lords built timber castles in the twelfth and thirteenth centuries. Still others began as natural features and acquired ritual or territorial significance over time. Poll An Ghearráin, meaning roughly the hole or hollow of the gelding, is a placename that suggests a landscape with its own local memory, though what relationship, if any, that name has to the mound itself remains unclear. Without excavation records or detailed field notes available in the open record, the mound keeps its own counsel.
