The Church of St. Agatha at College with its poly-chromatic marble was built between 1600 and 1610, in late-Renaissance style, on the site of a previous church, which had also been dedicated to St. Agatha. The façade was created by Natale Masuccio, and is decorated with frameworks on a light coloured background. It has a Greek cross plant, with splendid Baroque decorations including frescoes by Luigi Borremans (18th century). The work on the adjacent Jesuit College began in 1589 and were completed in the second half of 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.
