Thunstetten castle manor was built as a country manor house in the Bernese Oberaargau in 1711 to 1713 or 1713 to 1715. The castle was built for the Landvogt Hieronymus von Erlach following plans by the architect Joseph Abeille. The castle remained with the Erlach family until 1746. From 1746 until 1971 it had numerous owners. In 1971 the Stiftung Schloss Thunstetten (Thunstetten Castle Foundation) took over management of the building and grounds. Today rooms in the castle or the entire castle can be rented for events or meetings.
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.
