The Palace of Culture and Science is the tallest building in Poland and the eighth tallest building in the European Union. It is 231 metres tall, which includes a 43-metre high spire.
The building was originally known as the Joseph Stalin Palace of Culture and Science, but in the wake of destalinization the dedication to Stalin was revoked. The building was conceived as a 'gift from the Soviet people to the Polish nation', and was completed in 1955. The structure was built in three years according to the design of the Soviet architect Lev Rudnev. Architecturally, it is a mix of Stalinist architecture, also known as Socialist Classicism, and Polish historicism inspired by American art deco skyscrapers. Currently it is the headquarters of many companies and public institutions, such as cinemas, theaters, libraries, sports clubs, universities, scientific institutions and authorities of the Polish Academy of Sciences.
The tower was constructed, using Soviet plans, almost entirely by 3500 workers from the Soviet Union, of whom 16 died in accidents during the construction.

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.
