The Church of our Holy Lady, a fine example of Scheldt gothic, houses a number of important art objects: paintings by Antony Van Dyck and Gaspard De Craeyer among others, a skilfully sculptured pulpit, a marble high altar and several worthwhile mural paintings.
The showpiece is a romanesque baptismal font in blue stone of Tournai (11th century).
The original romanesque church was replaced by a gothic one in the shape of a Latin cross in the 13th century. During the following centuries, new elements were added to the building. A wooden spire, constructed in 1911, was blown down during a storm in 1940 and never replaced.
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.
