These circular enclosures, typically dating from the early medieval period between roughly the fifth and twelfth centuries, served as farmsteads and household compounds for families of varying social rank. Stone was the practical choice in areas where it lay close to the surface, and in the rocky landscapes of Connacht, cashels are a recurring feature of the countryside, though many have been robbed for field walls or simply absorbed back into the land.

Beyond its classification and location, the specific details of this particular cashel, its dimensions, its condition, the arrangement of any internal features, and whatever history might attach to its construction or later use, remain undocumented in publicly available form at present. What can be said is that Derryloughan More, like many Mayo townlands, carries the quiet archaeological weight of a landscape that was intensively settled during the early medieval centuries, and that a cashel here would fit a broader pattern of dispersed, family-based settlement that once covered this part of the west of Ireland. Whether the walls survive intact, as a low grassy ring, or only as a scatter of displaced stones is a question the site itself would have to answer.
