Enclosures of this kind, typically defined by an earthen bank, a ditch, or some combination of both, appear throughout the Irish landscape in considerable variety. They range from prehistoric ceremonial sites to early medieval farmsteads enclosed for protection, and without further detail it is not possible to say with confidence which tradition this particular example belongs to.

What can be said is that Lisbrogan sits within a county exceptionally dense with archaeological remains, where the bogland and marginal terrain have preserved earthworks that elsewhere were long ago ploughed away or built over. Mayo's enclosures, ringforts, field systems, and burial monuments speak to continuous human settlement stretching back several thousand years, and a named, catalogued enclosure at Lisbrogan is a marker, however quietly, of that same long story. The site has been noted and assigned a record, which in itself tells us that someone, at some point, recognised something worth preserving in the arrangement of the ground there.
