The Church of Our Lady (Vor Frue Kirke) is the cathedral of Copenhagen and the National Cathedral of Denmark. The present day version of the church was designed by the architect Christian Frederik Hansen in the neoclassical style and was completed in 1829.
There has been several several churches on this site since 1209. The cathedral has been rebuilt four times: The first church was burnt down and reconstructed in 1316. The second church was razed by a great fire in 1728 together with five other churches in Copenhagen and rebuilt in 1738. Finally during the bombardment of Copenhagen in 1807 the spire was hit by a Congreve rocket and nearly burnt the church down to the ground.
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.
