Château de Pibrac was built in 1540 to the site of older castle. It was damaged during the Revolution in 1794 and restored in 1887. The renaissance style residence is built of red brick. The castle itself consists of an old body and wings. The north wing is flanked by a round tower with terrace and has a staircase. The castle park, open to the public, was designed by the landscape architect Eugène Bühler in 1897.
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.
