The Christina church (or German Church) was consecrated in 1648 and named after Queen Christina. The octagonal chapel for Rutger von Aschenberg was built in 1681, possibly by Erik Dahlberg. The tower, designed by Carl Fredrik Adelcrantz 1780, rises powerfully over the lower urban buildings around it. It became an important symbol of the great German Assembly which included the Dutch who over a period in the 1600s represented a fifth of the city's population. Although the church was burnt on several occasions it managed to keep the walls of Dutch tiles from the 1630s. In an extensive renovation in 2001 the facades was covered with yellow plaster.
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.
