St Muredach's Cathedral

St Patrick's Cathedral is the Anglican cathedral of Killala and is one of the smallest cathedrals in Ireland. The present building was constructed in the 1670s, using rubble and stone from the medieval cathedral. The tower, spire and vestry were added to the building in 1817 by the architect James Paine.

At the instigation of Archbishop John McHale, Archbishop of Tuam, a new church was started in 1876, to a design by J.J. O???Callaghan. Much of the funding for the project came from the diaspora in the USA. This church was on a higher site opposite the original church. Progress slowed when the parish priest Canon James Magee died in 1885. His successor, Canon Patrick Lyons, demolished the half-completed church in 1891, much to the consternation of parishioners and donors, and built the present church alongside the old St Mary???s church. The present church, designed by Dublin architect, Walter G. Doolin , was started in 1897 and opened in 1901, dedicated to Our Lady of the Holy Rosary. James Pearse, the English father of Padraig Pearse, made the marble altar, and the stained glass was by Meyer of Munich, Germany. The large, five-lancet window over the altar, features images depicting scenes from the fifteen mysteries of the rosary, and was presented by the Archbishop of Tuam, Dr. John McEvilly.

St. Crumnathy's Cathedral is a former cathedral built in 1822. It was deconsecrated after it was closed for worship in 1997.
