That much is certain. Beyond the bare fact of its existence and its classification as an archaeological monument, the details remain, for now, unrecorded in any publicly accessible form. It sits in that particular category of Irish heritage that has been noted, mapped, and assigned a record number, but not yet fully described, a site known to exist yet waiting for its story to be told.

Enclosures of this kind are among the most common, and most varied, monument types in the Irish landscape. The term covers everything from the circular banks of an early medieval ringfort, which would have enclosed a farmstead and its outbuildings, to the more irregular boundaries of a later field system or ecclesiastical precinct. In Clare especially, where the landscape holds layer upon layer of prehistoric, early Christian, and medieval activity, a single earthwork can represent almost any period. Without further detail it is impossible to say what Brickhill's enclosure once contained or who built it, though the townland name itself, derived from the Irish, suggests a long-settled area where such remains are not unexpected.
