That single fact is, for now, almost all that is publicly known about it. The monument has been catalogued, assigned a record, and mapped, but the detail that would explain what it is, how old it might be, and what its original purpose was remains unavailable in any accessible public form.

Enclosures are among the most common and most varied features of the Irish archaeological landscape. The term covers everything from the circular earthen banks of a ringfort, a defended farmstead typical of the early medieval period, to the more irregular outlines of prehistoric settlement sites, burial enclosures, or the enclosed bawns of later tower houses. Without further information it is impossible to say which category the Ballybroghan example falls into, or whether it survives as an earthwork visible on the ground or exists only as a cropmark or a cartographic trace. Clare is a county with an exceptionally dense concentration of ancient monuments, particularly ringforts and cashels, the latter being stone-built versions of the same enclosure tradition, so the odds are reasonable that this site belongs somewhere within that broad continuum. But that is general probability, not specific knowledge, and the two are not the same thing.
