That spare description, an enclosure, is almost all that is formally recorded about it at present. In the landscape of Irish archaeology, an enclosure is typically a defined area bounded by earthen banks, ditches, walls, or some combination of these, and such features can date from the Bronze Age through to the early medieval period and beyond. They served many purposes: farming, settlement, ritual, burial. Which of these applies to Muckloon, if any single category even fits, remains an open question.

Muckloon is a small rural townland in Mayo, a county whose boglands and drumlin fields have preserved archaeological features that might have been ploughed away elsewhere. The enclosure there has been logged as a monument, which means someone, at some point, identified it as a feature of potential archaeological significance. Beyond that, the documentary record currently holds its silence. No excavation report, no detailed survey description, and no further historical context is available in the public record at this time.
