That designation alone suggests this is more than a straightforward Victorian or post-Famine burial ground, though the precise nature of what makes it significant remains, for now, incompletely documented in the public record.

The placename Lisheen is an anglicisation of the Irish loisín or lisín, a diminutive of lios, meaning a small earthen ringfort or enclosure. Placenames of this type often indicate early medieval settlement, and graveyards in such locations frequently turn out to be associated with a vanished church, a holy well, or a cillin, the term used for unconsecrated burial grounds where unbaptised infants were interred, typically at the margins of a parish or on older, pre-Christian ground. Whether Lisheen fits any of these patterns is not yet clear from what has been recorded, but the combination of monument status and a lios-derived placename hints at a long continuity of use at this particular patch of ground.
