Foundation The monastery of Dromore is believed to have been founded in the sixth century by
St Colman (called also Mocholmóc), probably the first Abbot of Dromore. The first building was a small
wattle and daub church on the northern bank of the
River Lagan. The Diocese of Dromore was established through the reorganisation of the Irish Church in the late 12th century, possibly at the synod held in Dublin in 1192 by the papal legate, Múirges Ua hÉnna, Archbishop of Cashel. The diocese coincided with the territory of the
Uí Echach Cobo, which later became the baronies of Upper and Lower
Iveagh, and the lordship of
Newry, County Down. by Dr. Michael Blake (bishop of Dromore 1833–1860) who had been Vicar-General of Dublin and the restorer of the
Irish College at Rome. This cathedral was enlarged and beautified by Bishop Henry O'Neill, who succeeded Bishop Thomas MacGivern in 1901. Under McGivern's predecessor, John Pius Leahy, O.P. (1860–1890), a
Dominican priory was founded on the Armagh side of Newry, and a church erected. The
Poor Clares, who went to Newry from Harold's Cross, Dublin, in 1830, were for many years the only nuns north of the
River Boyne. The
Sisters of Mercy founded a convent at Newry in 1855. Abbey Yard in Newry marks the site of the Cistercian abbey founded in 1144 by St. Bernard's friend, St.
Malachy O'Morgair, and endowed in 1157 by
Maurice O'Loughlin,
High King of Ireland. It is called in the annals
Monasterium de Viridi Ligno — a name given to Newry from the
yew-tree, said to have been planted there by St. Patrick, the Irish name being Niubar (and sometimes Newrkintragh, "the yew at the head of the strand") which is Latinized Ivorium or Nevoracum, but more commonly as above Viride Lignum. Since 2018, the Diocese of Dromore has remained without a Bishop. ==Allegations of sexual abuse==
