Rzeszów Castle - one of the main landmarks of Rzeszów rebuilt between 1902-1906, located on the former grounds of the castle of the House of Lubomirski. Currently the castle houses the seat of the provincial court, the building housed a prison up until 1981.
An early fortress stood on the castle's grounds since the sixteenth century. At the end of the same century, Mikołaj Spytek Ligęza built a Motte-and-bailey castle close by to the current castle's location. In 1620 he expanded the castle into a 'Palazzo in fortezza'. Since 1637 the castle was put under the ownership of the House of Lubomirski. Most of the building works were done by Tylman van Gameren and Karol Henryk Wiedemann. In 1820 the complex was brought under Austrian authorities; which adapted the building for a courthouse and a prison. The building was deconstructed at the beginning of the twentieth century due to its poor state. The only parts left from the original complex are the gatehouse and bastion fortifications.

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.
