The Parish Church of St. Stjepan was first mentioned in the 1100 AD, in the 'Glorious Dragoslav' grant. According to the Glagolitic inscription, it was expanded in 1510. It is dominated by elements of the Baroque and late Gothic works. Initially a single nave, the parish church in the 18th century, it became a triple nave by the merging a series of side chapels, which over the centuries were built into a one nave church. Above its entrance, there is a canopy of the unique name 'cergan', and from there it overlooks much of Kvarner. There was a bell tower next to the church, but in 1720 it was distroyed by lightning and a new one was built. The new one was not built in the same place, but in a nearby old cemetery, from where it still dominates the whole area today. This bell tower suffered devastation, by the Germans during the occupation of 1944, but was rebuilt after the war.
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.
