The Lutheran church of St. Catherine was built between 1788-1793. It is named after Empress Catherine II, who donated 28 000 silver roubles to the construction. The classicist-style building is a one naved church with large arched blind windows.
In the course of renovation in 1879, the spire received a new helmet and a clock with four faces. Supposedly architect Christoph Haberlandt made the design of the church. The altarpiece depicts Christ on the cross and is subject to protection by the state as a heritage of culture.
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.
