The majestic medieval castle of Sciacca was built in 1382 at the wishes of Guglielmo Peralta, count of Caltabellotta, who became one of the four vicars of the kingdom of Sicily after the death of king Fredrik the III. The castle was passed down to the counts of Luna when, after the death of Nicolò Peralta (son of Guglielmo) one of his three daughters, Margherita, married count Artale of Luna, a Catalan and uncle of king Martino.
The castle rises from its dominating position, in the high up, east part of the city, and is located within the perimeters of the ancient walls, that still exist in part today.It is tied to the “Caso di Sciacca”, the century-long bloody battle between the Catalan house of Luna and the Norman house of Perollo, in conflict over a secret love, that of Giovanni Perollo for Margherita, wife of Don Artale Luna, but also for political and economic interests.
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.
