The See of Dromore was founded in the sixth century by Colman of Dromore, and had its own independent jurisdiction ever since. The old cathedral of Dromore, which had been taken by the Protestants, was burnt down by the Irish insurgents in 1641, and rebuilt by Bishop Taylor twenty years later; the Catholic Church was erected later. The seat of the cathedral, however, was transferred some two hundred years ago to Newry, the largest town of County Down, and a place of great historical interest, situated at the head of Carlingford Lough. Newry Cathedral was begun in 1825 and completed in 1829. The cathedral was enlarged and beautified by Bishop Henry O'Neill, who succeeded Bishop McGivern in 1901.
