The Castello di Caccamo is among the largest and best preserved Norman castles in Sicily, and one of the largest in Italy. The castle is built on a steep cliff.
The castle as it is today was built by Matthew Bonnellus in the 12th century. It was later modified by the Chiaramontes in the 14th century, and by other rulers until the 17th century.
Caccamo castle is a large structure built of white stone, having an irregular plan. It has walls with V-shaped battlements, towers, a moat and a courtyard. The interior consists of a maze of rooms and stairways.
The most notable room within the castle is the Sala della Congiura, also known as the Conspiracy Hall. In 1160, some Norman barons met in this room to plot against William I of Sicily, but the rebellion failed.
The castle was inhabited by descendants of the Dukes of Caccamo until it was purchased by the Region of Sicily in October 1963. By this time, the castle was in ruins. Restoration work funded by the Region of Sicily began in 1974.
Today, the castle is open to the public. A restaurant called A Castellana is located on the ground level of the castle, while other parts of the structure are also used for conferences and meetings.
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.
