St. Jodok Church was founded in 1338 by the Duke Henrik XIV. The church was not yet fully completed, when it was destroyed by fire in 1403. During the reconstruction the chapels were extended (1435-1450). St. Jodok represents the Gothic style with late Gothic (15th century) and 19th century additions.
Of the many outstanding grave stones the particularly noteworthy are the tomb of Heinrich von Staudach (1483) in the crypt and the Peter von Altenhaus (1513 by Stephan Rottaler) under the gallery. The large baptismal font dates from c. 1520.
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.
