The name Ballaghboy derives from the Irish Bealach Buí, meaning the yellow road or yellow pass, suggesting the area carried some significance as a route or crossing point long before anyone thought to map its archaeology. The earthwork itself belongs to a broad category of field monuments that can include anything from the raised banks of a ringfort, a defensive enclosure used as a farmstead from the early medieval period onwards, to the remnants of a field boundary, a burial mound, or an enclosure whose original purpose has long been forgotten.
