The Duomo (Cathedral) of Enna, a notable example of religious architecture in Sicily, was built in the 14th century by queen Eleonora, Frederick III's wife. It was renovated and remodeled after the fire of 1446. The great Baroque facade, in yellow tufa-stone, is surmounted by a massive campanile with finely shaped decorative elements. The portal on the right side is from the 16th century, while the other is from the original 14th-century edifice. The interior has a nave with two aisles, separated by massive Corinthian columns, and three apses. The stucco decoration is from the 16th and 17th centuries. Art works include a 15th-century crucifix panel painting, a canvas by Guglielmo Borremans, the presbytery paintings by Filippo Paladini (1613), and a Baroque side portal. The cathedral's treasure is housed in the Alessi Museum, and includes precious ornaments, the gold crown with diamonds known as the 'Crown of the Virgin,' Byzantine icons, thousands of ancient coins, and other collections.
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.
