Enclosures of this kind, which survive across Ireland in considerable numbers, are among the most enigmatic features of the rural countryside. They can represent the remains of a ringfort, a cashel, a monastic enclosure, or a field boundary of indeterminate age, and without excavation or detailed survey it is often impossible to say which. What they share is a tendency to endure quietly, overlooked by roads and visitors alike, their circular or sub-circular outlines visible as earthen banks, ditches, or crop marks depending on the season and the soil.

Ballygommon is a small townland in Mayo, a county whose landscape is densely layered with prehistoric and early medieval activity. The west of Ireland in particular preserves a remarkable density of earthwork enclosures, many of them associated with the early medieval period roughly between the fifth and twelfth centuries, when ringforts served as the primary form of enclosed farmstead across the island. Others predate this period entirely. Without further detail attached to this particular site, its date, function, and condition remain open questions, which is itself a reasonably accurate reflection of how much of the Irish archaeological record still stands.
