The Church of Snowy Mary was first mentioned in the year 1404. A rich lady from Piran donated the money for its construction. A Baroque altar from the 17th century decorates the presbytery. There are many paintings on the walls, in wooden and fretted frames, made in the year 1666 by B. Marangoni from Mantova.
On the east side, above the entrance, there is the main painting from the second half of the 17th century portraying the wonders of snow. The paintings of the Crucifixion and Revelation were discovered on the arch wall in the year 1969. The painting of the Revelation dates from the year 1430 and is the work of a Venetian painter. The Crucifixion on a pointed Gothic arch was painted later, between the years 1450 and 1460. It was presumably painted by art master Nicolo di Antonio from Piran, who worked in Padova, as substantiated by various archive sources.
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.
