The Clementinum (Klementinum), one of the largest collections of historic buildings in Europe, is home to the National Library of the Czech Republic. 

These beautiful Baroque buildings were originally part of a Jesuit College, and later came to house the Jesuit book collection, as well as the collection from the Karolinum.

 The library eventually became the property of the state after the Jesuits were expelled, and the Clementinum became a public library in 1782 shortly after being constituted as the National Library.
