The Church of Saint Catherine (Chiesa di Santa Caterina) is a synthesis of Sicilian Baroque, Rococo and Renaissance styles.
In 1310 the last will of the rich Benvenuta Mastrangelo determined the foundation of a female monastery under the direction of the Dominican Order. The new monastery was dedicated to Saint Catherine of Alexandria and was erected in the area where the old palace of George of Antioch, admiral of Roger II of Sicily, stood.
In 1532 the widening of the building was decided. Between 1566 and 1596 the church was rebuilt under the supervision of the Mother Prioress Maria del Carretto. The church was inaugurated on 24 November 1596.
During the 19th century the church was damaged on several occasions: during the uprising of 1820-1821, the Sicilian revolution of 1848, the Gancia revolt, the insurrection of Palermo (1860) and the Sette e mezzo revolt (1866).
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.
