Marchione castle was a hunting lodge of the Acquaviva of Aragona, counts of Conversano, from around the year 1000 AD. The sumptuous building, with a rectangular shape and four cylindrical keeps on the corner, has been built on three floors. The ground floor, the mezzanine and the four towers date back to the Middle Ages, while the upper floor dates back to the Neoclassic- Baroque age, maybe a work by the school of Vanvitelli.
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.
