Charleroi Belfry is part of the City Hall, designed by architect Joseph André in 1936. It is a perfect blend of Classicism and Art Deco. The 70-metre-high belfry can be accessed by climbing 250 stairs and was built using blue and white stone and bricks. It is crowned with a small bronze tower. The last three levels are reserved for the chambers of the 47 bells forming the carillon. Every fifteen minutes it chimes out a few bars of folk songs by Jacques Bertrand, the bard of Charleroi. This belfry is a UNESCO world heritage site.
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.
