The Oratory of Saint Lawrence was founded in the late 16th century. The building was given to the Conventual Franciscans in order to spread the cult of the saints Francis and Lawrence. In 1699 Giacomo Serpotta realized a sumptuous stucco decoration.
The oratory is particularly famous because of the masterpiece altarpiece Nativity with St. Francis and St. Lawrence (1600 or 1609) by Caravaggio. This important painting was stolen, probably by Cosa Nostra, on October 18, 1969. In 2015 a hi-tech replica of the altarpiece was placed inside the oratory.
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.
