The Venosa Castle is a historic fortified building located in the homonymous town in the province of Potenza. Commonly referred to as the Aragonese Castle because it was built by Duke Pirro del Balzo during the Aragonese dynasty period, it is situated at the southern end of the plateau occupied by the urban area of the city.
Its construction dates back to 1470, commissioned by Duke Pirro del Balzo as part of a broader fortification project. It is an imposing structure, with a square plan featuring four cylindrical towers. The Del Balzo coat of arms, a radiant sun, is visible on the western tower. The construction of the castle and the excavation of the moat, in accordance with the new principles of fortification, led to the demolition of the Romanesque cathedral and the surrounding district. Therefore, a new cathedral was built in an expansion of the settlement on the lower part of the plateau where the city stands.
It was transformed from a fortress into a noble residence by Carlo and Emanuele Gesualdo, with the addition of the inner loggia, the northwest wing, and the outworks at the base of the towers. From 1612, it hosted the Academy of the Renaissance.
The four cylindrical towers at the corners, initially crowned with battlements and probably conical roofs, are supported by outworks that constitute the scarp of the moat, used as prisons. The entire building, accessed via a drawbridge, is surrounded by a deep moat. Inside, there is a large courtyard surrounded by a Renaissance loggia. In front of the castle, there is a porticoed square and a monumental fountain granted to Venosa by Charles I of Anjou.
Within its walls, in the rooms located in the basements of the towers, the castle houses the National Museum of Venosa, which primarily preserves the rich evidence of the Roman colony of Venusia.

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.
