Saint-Lizier Cathedral can refer to either of the two former co-cathedrals of the town of Saint-Lizier, Notre-Dame Cathedral (Cathédrale Notre-Dame-de-la-Sède de Saint-Lizier) and St. Lizier's Cathedral (Cathédrale Saint-Lizier de Saint-Lizier), dedicated to Saint Lycerius.
Saint-Lizier falls into two quite separate parts, each with its own cathedral. The lower part contains the old village around the Cathedral of Saint Lizier while the upper part, surrounded by ancient fortifications, includes the Bishop's Palace.
St. Lizier's Cathedral features an octagonal tower and attractive cloisters with a balcony and interesting carved stone decorations at the top of the columns. There are a large number of ancient (11th century) frescoes inside the cathedral.
The cathedral is part of the UNESCO World Heritage Site of Routes of Santiago de Compostela.
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.
