Roughly 33 metres across, it survives now as little more than a low bank at its north-western edge, the rest of its outline interrupted by later quarrying and cut through at east and west by a field wall. It is the kind of site that rewards patience rather than spectacle; you are looking at a shape more than a structure, a faint argument in the land rather than anything a casual eye would immediately recognise.

Circular enclosures of this type are among the most common, and least understood, monument types in the Irish landscape. They may have served as enclosed farmsteads, as spaces for livestock, or occasionally as sites with ceremonial significance, and without excavation it is rarely possible to say which. What survives at Lisheen represents the outermost boundary of whatever once stood here, and even that has been considerably reduced. The quarrying that removed part of the north-eastern sector was presumably agricultural or industrial in origin, and the field wall cutting across the monument tells its own quiet story about how the land was reorganised in later centuries, with earlier features absorbed into the working patterns of farms that had no particular reason to preserve them.
