The Cathedral of the Immaculate Conception in Sligo was developed by Bishop Laurence Gillooly who had been appointed Bishop of Elphin in 1858. He decided that the diocese was now of a size and wealth that the time had come to replace St. John's Parish Chapel, which had been recognised as the diocesan pro-cathedral.
He engaged George Goldie, one of the foremost Catholic architects in England in the nineteenth century. The cathedral was opened for divine worship on 26 July 1874 by Cardinal Paul Cullen of Dublin.
Modelled on a Normano–Romano–Byzantine style, it is the only example of a Romanesque style cathedral built during the 19th century. Designed in the shape of a basilica, the church has a square, pyramid-capped tower, which reaches a height of 70 metres, and supporting turrets at the west end. The circular baptistery incorporated in the apse with its five lancet windows behind the high altar, was originally designed as a mortuary chapel.
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.
