The Plasy Monastery was founded in 1144 by Duke Vladislav II as one of the oldest Cistercian monasteries in Bohemia. Monks from the Franconian Langheim settled Plasy. During the Hussites Wars in the first half of the 15th century buildings of the abbey were burnt out and almost all the goods were subsequently taken.
The monastery experienced a second period of prosperity after the Thirty Years‘ War: the baroque new buildings of the monastery, the large foursided courtyards and the pilgrimage church of Marianske Tynice are still characteristic of the landscape today – as are extensive agricultural areas for grain and fruit cultivation.
In 1826, the monastery building with the whole estate was purchased by Klemens von Metternich, who is buried in the Church of Saint Wenceslaus in the family tomb.
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.
