The Baroque Library Hall in Prague, capital of the Czech Republic, is one of the most beautiful libraries in the world. It opened in 1772 and is part of a historic building complex called Klementinum. It has a collection of over 20000 books, mostly on religious literature. The paintings on the celling- called frescoes- depict themes from science, art and education, and portraits of Jesuit saints. Among the other displays are rare globes and astronomical clocks. Currently, a part of the library is being digitized. The historical books may not survive forever, but at least the content will.
