St Patrick's Cathedral

The Cathedral Church of St Patrick, Killala, is one of Ireland’s smallest cathedrals but also one of its oldest. “The Episcopal See of Killala appears to have been founded between the years 434 and 441, by St. Patrick, who, during that period, was propagating the faith of Christianity in the province of Connaught; and built a church at this place, called Kill-Aladh, over which he placed one of his disciples, St. Muredach, as bishop.”
