The Klementinum library was first opened in 1722 as part of the Jesuit University. This is an exquisite example of Baroque architecture. It gives spaces to over 20,000 books. Our readers have voted the library as one of the most beautiful and majestic libraries in the world.
Jan Hiebl painted the ceiling frescoes of this library in Prague. The director Karel Rafael Ungar established Biblioteca Nationalis, a collection of Czech language literature in 1781. The library has sent some of the rare historical books to Google for scanning and will eventually be available on Google Books.
This Prague library is a rare and little-known treasure and it is associated with several little-known facts such as the Klementinum used to be the third-largest Jesuit college in the world; recording of local weather began there in 1775 and had continued ever since; it is featured in a novel by famous Spanish-language writer Jorge Luis Borges.
