Scicli was founded by the Sicels (whence probably the name) around 300 BCE. In 864 CE, Scicli was conquered by the Arabs, as part of the Muslim conquest of Sicily. Under their rule it flourished as an agricultural and trade center.
In 1091, it was conquered from the Arabs by the Normans, under Roger I of Hauteville, after a fierce battle. Following the various dynasties ruling the Kingdom of Sicily, it was an Aragonese-Spanish possession before being united in the Kingdom of Italy in the mid 19th century.
Following a catastrophic earthquake in 1693, much of the town was rebuilt in the Sicilian baroque style, which today gives the town the elegant appearance which draws many tourists to visit it. Alongside seven other cities in the Val di Noto, it has been listed as one of UNESCO's World Heritage Site in the list of Late Baroque Towns of the Val di Noto.
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.
