The Archdiocese of Armagh (Latin: Archidioecesis Ardmachana; Irish: Ard-Deoise Ard Mhacha) is a Roman Catholic archdiocese in the northern part of Ireland. The archdiocese is led by the Roman Catholic Archbishop of Armagh who serves as pastor of the mother church St Patrick’s Cathedral and Metropolitan of the Metropolitan Province of Armagh. It’s claim to pre-eminence in Ireland as the primatial see rests upon its traditional establishment by Saint Patrick circa 445.
