The first reliable evidence of feudalism in Bivona dates back to 11 October 1299, when Robert of Anjou, the King of Naples, granted the castles of Bivona and Calatamauro to Giacomo de Catania. The castle mentioned in this decree was probably a watchtower which had been built as part of the walls of Bivona around the time of the War of the Sicilian Vespers.
Eventually, the castle began to be built in the first half of the 14th century. In 1359, Guido and Francesco Ventimiglia almost destroyed it, but it was rebuilt within the same year by Corrado Doria. The land and castle of Bivona was passed to Nicholas Peralta in 1397. In 1406, it belonged to Francesco Castellar.
The castle was looted and partially destroyed in 1529, during the Secondo caso di Sciacca, a conflict between the de Luna and Perollo noble families.
Today, the castle is in ruins. Some parts of it are embedded in structures of a later period.
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.
