Sunnersberg medieval church dates back to the 1200s, but it has been enlarged and reconstructed several times. Fire damaged it badly in 1583. The most remarkable detail is an altarpiece, which is painted by famouse Flemish Baroque artist Anthony van Dyck in 1620. It was donated to Sunnesberg church by Clas Julius Ekeblad in 1779. The pulpit was donated by Magnus Gabriel De la Gardie in 1670.
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.
