After the Roman town of Burdigala (current Bordeaux) ceased to exist, the inhabitants moved away from the river, and the new city centre became what is now the Saint-Pierre district. The first church was built on the premises of the former port in the Middle Ages. The current church dates from the 14th and 15th centuries and was built on the site of ancient Gallo-Roman port. The Flamboyant style appearance survived from the renovation in 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.
