Branzoll Castle was built around the year 1250 by the Lords of Sabiona. Between 1465 and 1671, it was the site of the Prince-Bishop's court judge. In 1671, it was destroyed in a fire. In 1895, reconstruction began. While the castle-keep still contains parts of the former fortress, the residential tract is completely new. The view from the church square of the buildings on both sides and the castle looming over it all is among the architecturally most breathtaking sights the city has to offer.
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.
