Raths, or ringforts, are roughly circular enclosures defined by one or more earthen banks and ditches, built predominantly during the early medieval period, roughly between the fifth and twelfth centuries. They served as farmsteads and homesteads for the farming families of Gaelic Ireland, and an estimated forty to fifty thousand of them survive across the island in varying states of preservation. The one at Lahardaun is among them, sitting in a county already thick with early medieval and prehistoric remains.

Mayo's landscape has a particular relationship with this kind of monument. The region was well settled during the early medieval period, and ringforts here tend to occupy slightly elevated ground, often with commanding views over bog, field, or coastal inlet, positions that made practical sense for a farming household alert to both the weather and its neighbours. The rath form itself varied considerably: some were simple single-banked enclosures enclosing a house or cluster of outbuildings, while others were more elaborate multivallate structures suggesting higher social status. Without more detailed survey information specific to this site, it is not possible to say which category the Lahardaun example falls into, how well preserved its banks remain, or whether any internal features survive. What can be said is that its presence in this townland places it within a long continuum of human settlement in north Connacht, one that stretches back well before the Norman arrival and continued largely undocumented except in the ground itself.
