The first historical evidence of the Caracciolo Castle existence dates back to 1237. However, the origin of the stronghold is undoubtedly older, and historical research suggests that an initial form of fortification may have existed when the Lombard populations founded the first settlement on the hill in the 7th century.
Subsequently, ownership of the castle passed from the Angevins to the De Porcellis family, who administered it for a brief period before transferring it to a branch of the noble Caracciolo family, originally from Naples. In 1561, at the behest of Marcantonio Caracciolo, the main tower)was transformed into a prison, while the rest of the castle continued to serve as a residence. The Caracciolo family gradually expanded the castle and made it their permanent settlement. In 1783, Litterio Caracciolo enlarged and enriched the fortress with numerous works of art.
Following the earthquake of 1857, the fortress was in a state of abandonment, and Baron Barracco and his heirs lacked the financial means to initiate restoration work.
Caracciolo castle stands to the north on the steep hill of the town and is surrounded by two rivers, the Torrente Pergola and the Fiumicello. The castle, of medieval origin, has been modified and expanded several times throughout history.
Its current appearance is the result of a restoration following the earthquake of 1980. Currently, it is owned by the Municipality of Brienza, which is carrying out restoration work and an urban regeneration process that encompasses the entire medieval village below the fortress. Historically, both the village and the castle were part of the Principality of Citra until 1811 when they became part of the territory of the current Basilicata Region.
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.
