Châlons Cathedral is a Roman Catholic church in Châlons-en-Champagne. The cathedral is the seat of the Bishop of Châlons and was consecrated in 1147 October 26, by Pope Eugene III.
Jean-Jacques Arveuf-Fransquin designed the neo-Flamboyant organ case of Châlons Cathedral. The case was created by the cabinetmaker Etienne Gabriel Ventadour, and housed the instrument made by John Abbey, who delivered the instrument in 1849. The cathedral is also noted for its stained glass windows.
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.
