Clementinum

The Clementinum (Czech: Klementinum) is a historic complex of buildings in Prague which houses the National Library of the Czech Republic.

Until recently the complex hosted the National, University and Technical libraries; the City Library was also nearby on Mariánské Náměstí. In 2009, the Technical library moved to the Prague National Technical Library at Technická 6. The Municipal library is located in the adjacent building on Mariánské Náměstí, where you'll find the famous Idiom installation (known as the book tower) in the foyer.
