Cill Bhríde, meaning the church of Brigid, points to one of the oldest layers of Irish religious settlement, those early ecclesiastical sites established under the patronage of Saint Brigid of Kildare, whose cult spread across the island from the fifth and sixth centuries onwards. That a graveyard in County Mayo still carries this dedication suggests a continuity of use stretching back well over a millennium, even if the physical remains above ground offer only fragments of that longer story.
