Nový zámok (literally 'New Castle') is a six-floor Renaissance building with four bastions. It was constructed in 1564–1571 as a watch tower during the Ottoman wars. Because of its dominant position, it was also used as the town's live clock (exact time was announced every quarter of an hour on a trumpet).
A permanent exhibition called Anti-Turkish Wars in Slovakia is installed on four floors of the castle. The highest floor offers a panoramic view of Banská Štiavnica and its environs.
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.
