The Church of Virgin Mary is a three-aisle basilica church (the nave is higher than the aisles) with large separated chancel closed by five-side apse. It was erected in the second half of the 14th century and enlarged in 1500s. The church was partially damaged during II World War and rebuilt in 1948. In 2003 the spire and dome of the church tower were reconstructed.
More valuable monuments in the temple are pulpit coming from late Renaissance made in 1609-1630 by master from Słupsk, Paweł Waltersdorf and funded by the guilt of amber-processors (with 43 members at that time). The pulpit is covered with bass-relieves, richly ornamented polychromed and gilded. The entrance to the pulpit is embraced by a portal (the lock in the door comes from 1609). Marvelous, first final of the pulpit, the so called amber crown from the first half of the 17th century was taken away during II World War. Worth attention are also hanging candelabra – some Baroque from the 18th century, some Neo-Rococo from the 19th century – as well as numerous Baroque candlesticks form the 17th-18th centuries and later from the 19th century.
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.
