Enclosures of this type are among the most common archaeological features in Ireland, and among the least understood. The term covers a wide range of structures, from the circular earthen banks of a ringfort, which would have enclosed a farmstead in the early medieval period, to prehistoric ceremonial boundaries or later pastoral enclosures whose purpose is harder to pin down. Without more detail about this particular example, the category itself is what the place currently offers.

Lisduff is a townland name with some resonance. The Irish "Lios Dubh" translates roughly as "black fort" or "dark enclosure", and lios is one of the standard words for a ringfort, suggesting that the landscape here has carried some memory of an enclosure, earthen or otherwise, long enough to become embedded in the place name itself. Whether the monument recorded here is the same feature that gave the townland its name, or a separate and perhaps older structure nearby, is the kind of question that fieldwork and closer examination might eventually answer.
