The ruins of Czorsztyn Castle stands at the top of the hill nearby Dunajec. According to Jan Długosz, in 1246 the owner of the castle was Piotr Wydżga. However that theory was never after confirmed by other historians, so the beginnings of castle functioning are dated on 14th century. Large development of the castle took place during the reign of Casimir III the Great. In years 1629–1643, when Jan Baranowski was a starosta of Czorsztyn, the castle was fundamentally rebuilt. In 1790 the roof of the castle burnt after a thunder clap. In the result castle was quickly broken down and became empty.

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.
