    Additional Information


    Primatial see of Ireland. Saint Patrick built a stone church on Ard-Macha (the Hill of Macha; Macha was a legendary queen), and made it his see in 445 in the papacy of Pope Saint Leo the Great. He held a synod here in 448, one of the still-extant canons of which states that cases of conscience, if too difficult to be disposed of by the Archbishop of Armagh, should be referred to the See of Rome. King Brian Boru captured the city in 1004, but acknowledged its primacy; he was buried here. Formally elevated to an archdiocese in 1152 by Pope Eugene III. The 12th-century cathedral, built on the site of the church built by Saint Patrick, has been in Protestant hands since the Reformation. The last historical mention of the Culdees is at Armagh in 1633, when they were incorporated in the Catholic cathedral chapter by Primate Hugh O’Reilly; to this day, their estates belong to the “vicars choral” of the Protestant cathedral.
