The site is associated with the ancient parish of Brigown, whose name derives from the Irish Bruighean Eoghanacht, pointing to early medieval Eoghanacht tribal territory in this part of Munster. That depth of time is not always obvious from the ground, but the graveyard's continued use across many centuries, long after the parish structures around it shifted and changed, gives it an unusual layered quality that sets it apart from more straightforwardly legible historic sites.

Brigown was an early ecclesiastical foundation, and the townland retains the name even as much of the surrounding area became absorbed into the civic geography of Mitchelstown. Medieval parish graveyards of this kind often accumulated burials over a span of eight or nine centuries, and Brigown is no exception. The remnants of the old parish church, roofless and ivy-grown for generations, stand within or adjacent to the burial ground, as was standard practice in Irish ecclesiastical sites where the church and its graveyard formed a single bounded enclosure. These enclosures sometimes follow the outline of even earlier Christian or pre-Christian sacred spaces, the circular or ovoid shape of the surrounding ground occasionally betraying origins that predate the Norman reorganisation of the Irish church in the twelfth century.
