St. Florin' s Church is a triple-naved Romanesque pillared basilica (founded in the 12th century) with Gothic chancel (1350) on Roman tower. The original flat timber ceiling was renewed in 1708, and the squat towers were replaced in 1900 by pointed ones. Nearby is the city's oldest dwelling house.
Opposite, where the vicarage belonging to the Church of our Beloved Lady now stands, is the site where the central section of the Franconian royal court originally stood in the 6th century.
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.
