St. Rochus Cemetery (Rochusfriedhof) was created in late 1510s to bury the victims of the plague epidemic of 1517-18. To avoid spreading the disease, city authorities decided to build the cemetery at some distance from the city, so St. Rochus is located outside the old city wall. The cemetery was finally consecrated on 21 March 1519. St. Rochus Chapel was built in 1520–21. The architect was Hans Beheim the Elder, who also built a chapel for Johannisfriedhof, another old Nuremberg cemetery.
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.
