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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
