The Abbey of Saint-Evroul is a former Benedictine abbey, today in ruins. Its name refers to its founder, Ebrulf (Evroul), who founded a hermitage in the forest of Ouche around 560. The abbey was rebuilt around 1000. Robert de Grantmesnil served as abbot of Saint-Evroul, which he helped restore in 1050. He had become a monk at Saint-Evroul before becoming its abbot. Orderic Vitalis entered the abbey as a young boy and later wrote a history of the abbey. Saint-Evroul was famed for its musical programme and eleven monks brought its musical traditions to the abbey of Sant'Eufemia (now part ot town of Lamezia Terme) in Calabria. The abbey was rebuilt again between 1231 and 1284. In 1628 it was closed and demolished finally in the early 1800s.
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.
