St Macartan's Cathedral, Clogher is one of two cathedral churches in the Diocese of Clogher in the Church of Ireland.
According to tradition a monastery and bishopric were founded in Clogher circa 490 by St. Macartan on the orders of St. Patrick.
In 1041, the church of Clogher was rebuilt, and dedicated to the memory of St. Macartin. It was again rebuilt in 1295 by Matthew M'Catasaid, Bishop of Clogher, but burnt to the ground on 20 April 1396 along with two chapels, the abbey, the court of the bishops, and thirty-two other buildings with all their contents. In 1610 the abbey and its revenues were confiscated by King James I and given to the Diocese of Clogher. The present building was erected on the site in 1744 by architect James Martin in a neo-classical style.
References:The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
