It is not known when the Przeclaw Renaissance palace was built. Originally, it was made of wood, and by 1578, belonged to the Ligeza family. In the late 16th century, it was purchased by the Koniecpolski family, which built a new, stone structure. In 1658, the castle was bought by Governor Wladyslaw Rey. The castle remained in the hands of the aristocratic Rey family until its confiscation by the communist regime in 1944. The Rey family had been active during the war in the anti-German underground movement Armia Krajowa and its organisation Tarcza Opieka providing shelter to fugitives, including Jews, and material support to the Polish Resistance. Armia Krajowa members and landowners being persecuted after the war by the communist regime, the Rey family had to go into exile to France. The palace has not been returned to its former owners and is currently a restaurant and a hotel and open to visitors.
References:The Clementinum is a historic complex of buildings in Prague. 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.
