According to archaeological finds, there was a Slavic settlement already in the 6th-7th century in Libušín. At the end of the 9th century, a gord was built here. The Church of Saint George was probably founded in the 10th century in the gord's area. In 1650 the church took its current Baroque shape. The area of Church of Saint George and remains of the gord include a wooden bell tower built in 1500.
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.
