Inowłódz Castle was built by king Casimir the Great in 1356-1366. Its function was to protect the customs chamber located on the Pilica ford, lying on the trade route running from Lwów, through Sandomierz to Toruń. Inowłódz and his ford were of strategic importance, cutting in between Mazovia and Lesser Poland.
The first recorded castle castellan was Piotr Tłuk from Strykowie family. At the end of the fourteenth century, the castle belonged to the Niemirowie family, however, Władysław Jagiełło bought it and due to its important location, restored to royal property. In connection with the deterioration of relations with prince Siemowit IV, the king predicted a threat from Mazovia and wanted to have an important, border stronghold. At the turn of the 14th and 15th centuries, he visited Inowłódz many times, presumably controlling the castle’s repairs and its reconstruction. The interior development was considerably expanded, perhaps to increase the larger crew.
In 1515, the castle was bought by Adam Drzewicki, a representative of a wealthy Polish noble family, and in the mid-seventeenth century, the Lipski family became its owner. In times of Drzewickis, after 1563, the second significant reconstruction of the castle was carried out, caused by the fire that destroyed the building. As a result of the Polish-Swedish war in 1655-1657, the castle was destroyed and gradually fell into ruin.

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.
