St. Urban Tower is originally a Gothic prismatic campanile with a pyramidal roof. It was erected in the 14th century. A church bell installed in the tower has been dedicated to Saint Urban, the patron of vine-dressers. The bell was cast in a mould by the bell-founder Franciscus Illenfeld of Olomouc in 1557. Its weight is 7 tonnes.
In 1775 the pyramidal roof was constructed with annion in the Baroque style with an iron double cross. An archade passage was erected around the tower in 1912. There are 36 old gravestones (coming from the 14th and 15th centuries, one of these comes from the Roman Empire and dates back to the 4th century) bricked into the exterior walls of the St. Urban Tower.
In 1966 the tower was damaged by fire and the St. Urban Bell was destroyed as well. The reconstructed tower was reopened in 1971. The renovated bell was located in the front of the tower and a copy of the bell (made by employees of VSŽ Steel Works Košice in 1996) was installed in the campanile.
The East Slovak Museum set up an impressive exhibition of foundrywork in the tower after the reconstruction in 1977. It was removed in 1995. Today, there is a unique wax museum exhibition in the tower.
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.
