A castle (cum castro) in Żywiec was first mentioned in 1467, as destroyed by an army, under Casimir IV Jagiellon's command against the House of Komorowski, with the Korczak Coat of Arms, recorded by Jan Długosz. However it is not certain whether it denoted the castle in the town or a fortifications on a nearby Grójec hill. Archaeological scrutiny dates the origins of the castle in the first half of the 15th century. A later expansion was constructed in 1567 by the House of Komorowski. Under the ownership and will of Jan Spytek Komorowski, during the castle's expansion a Renaissance style courtyard was built, which is still untouched in its current form.
Since 2005, the Old Castle in Żywiec hosts the City Museum in Żywiec. The Old Castle's permanent exhibition includes an ethnographical exhibition - which completes the Wooden Architecture Trail in the Silesian Voivodeship, in Poland.
Żywiec's Old Castle is encompassed by a 260,000 square metre landscape park, which was established initially in the 17th century.

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.
