On Sunday, July 4, at 11 am, the 
Pro-Cathedral in Dublin welcomes the  Cornelia Connelly School Advanced Women’s Ensemble and Handbell Ensemble  from Anaheim under the direction of  Brian Dehn.  St Mary's  Church (Irish: Leas-Ardeaglais  Naomh Muire), known also as St Mary's Pro-Cathedral or  simply the Pro-Cathedral, is a pro-cathedral  and is the episcopal seat of the Roman Catholic Archbishop of Dublin  and Primate of Ireland.
Saint  Mary’s was constituted in 1825 from Saint Mary’s Chapel Liffey Street,  whose pre-Reformation monastic antecedent was the great Benedictine, and  later Cistercian Abbey of Saint Mary’s founded in the twelfth century.  The present church is built on a site which was part of the ancient  monastic foundation. The church was dedicated on 14th November 1825, the  Feast of Saint Laurence O’Toole, Patron Saint of the Archdiocese of  Dublin under the patronage of the ‘Conception of the Virgin’.
Music has always been a central ministry in Saint Mary's Pro  Cathedral. The Palestrina Choir is the resident choir of Saint Mary's  Pro-Cathedral. It had its origins in a boys' choir formed in the 1890s  by Dr. Vincent O'Brien, then a music teacher at St. Mary's Place Christian Brothers School  in Dublin. It was at a performance of Palestrina's Missa Papae Marcelli at St. Teresa's Carmelite Church in Clarendon Street in 1898  that this choir came to the attention of Edward Martyn their founding  sponsor. Martyn wished to promote the music of Palestrina which was  espoused by Pope Pius X as a standard to which liturgical  music should aspire. The Palestrina Choir was constituted and installed  in the Pro-Cathedral on January 1st, 1903 with Dr O'Brian as director. In the century since its foundation, the Choir has had seven  Directors. Dr Vincent O'Brien, Director until his death in 1948, was  succeeded by his son, 

Oliver. In 1978, Fr Seán O hEarcaigh took over the  baton from Oliver O'Brien. He was succeeded in 1982, by Ms. Ite  O'Donovan and in 1996 by Comdt Joseph Ryan. Ms. Órla Barry was the  Director from the end of 1996 to 2001. The current Director is Blánaid  Murphy. Over the years the Palestrina Choir has attracted singers of  high renown. John Count McCormack was a member of the Choir from 1904 to  1905. Many recent members are now distinguished soloists, most notably  Emmanuel Lawler, who began his singing career as a boy soprano in the  Choir. In recent years, the Choir has travelled widely, singing at many  Cathedrals and venues throughout Ireland, Europe and North America.
