Lilienfeld Abbey was founded in 1202 by Leopold VI, Duke of Austria and Styria, as a daughter house of Heiligenkreuz Abbey. Successive abbots acted as councillors to the rulers of Austria, and the abbey became wealthy as a result of this valuable connection.
Abbot Matthew Kollweis (1650-1695) turned the monastery into a fortress during the Turkish advance against Vienna in 1683, installing a garrison and giving shelter to a large number of fugitives.
In the 17th century the medieval buildings were extended by Baroque additions. In the first half of the 18th century the tower, library and church interior and furnishings were also refurbished in the Baroque style.
The abbey was suppressed by Emperor Joseph II in 1789, but although the library, archives and portable valuables were removed, on the death of Joseph II it was reopened by Emperor Leopold II as early as 1790.
In 1810 much of the abbey was destroyed in a fire, but was rebuilt under Abbot Johann Ladislaus Pyrker, who later became the Patriarch of Venice (1820-26) and eventually Archbishop of Eger.
As part of his endowment, Duke Leopold VI, Duke of Austria, granted the Abbey lands in and around Pfaffstätten, between Baden and Gumpoldskirchen, upon which the monks erected a walled estate. This estate, the Lilienfelderhof, comprising a gothic church, manor house, and numerous other buildings, was acquired in 2006 by the Kartause Gaming Private Foundation via a 99-year leasehold. The property and its vineyards are currently in the process of being restored and revitalised.
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.
