That much is recorded. Beyond the bare designation, the site belongs to a category of place that appears frequently across the Irish landscape: a location where religious life was once organised, where a community gathered, and where the physical evidence has since reduced to ground-level traces or disappeared entirely into farmland and grass. The name Carheens itself, likely derived from the Irish "ceathrúna" or a related diminutive form suggesting small quarters or divisions of land, hints at a settled, parcelled landscape with its own long history of use.

Church sites of this kind in the west of Ireland often have roots stretching back to the early medieval period, when small, locally founded oratories and chapels served dispersed rural populations. Many were associated with a patron saint whose name has since been lost from local memory, or survived only in the name of a nearby holy well or festival day. In Mayo particularly, such sites frequently continued in use through successive centuries, sometimes into the post-medieval period, before falling into disuse as parishes were reorganised or populations shifted. What remains on the ground at Carheens, whether collapsed walling, a raised enclosure, a scatter of worked stone, or simply a field boundary that traces the outline of something older, is not currently documented in any publicly available form.
