Holy Trinity

Holy Trinity Church, also known as Father Mathew Memorial Church, is a Roman Catholic Gothic Revival church and friary on Fr. Mathew Quay, on the bank of the River Lee in Cork. It belongs to the Order of Friars Minor Capuchin and is the only church dedicated to Father Theobald Mathew.

The building's listing in the National Inventory of Architectural Heritage describes it as a "Regency Gothic-style church with Gothic-Revival portico", and it is "one of the first large churches in the south of Ireland to be built in this style." Construction of the church began in the early 1830s but stalled shortly before the Great Famine. It would only be completed in 1890, in time for the centenary of the birth of Fr. Mathew. The church features several noteworthy stained glass windows, including three by Harry Clarke's studio and a large memorial to Daniel O'Connell.
