Abbey Sainte-Marie du Rivet may be founded in the late 8th century. There are some remains of the 9th century fortifications and the abbey church was built in the 13th century. The community is affiliated to the Cistercian order in 1189: at this date, the monastery already bears the name of Sainte-Marie.
The abbey was ravaged during the French Wars of Religion and in 1702 there was only one monk left. In 1938 the abbey came back to life, with a community of nuns. Today, 14 nuns live in the Rivet Abbey. They are Trappistines, that is to say they belong to the Cistercian order of Strict Observance, which is an order stemming from the Cistercians of the Common Observance, themselves from the Benedictines.
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.
