Bellomo Palace Regional Gallery is situated in the premises of Bellomo Palace. The origins of the palace have been traced to the 12th century, the time of Hohenstaufen rule of Sicily. The palace still features a number of unusually well-preserved elements from this time. The main facade, as well as the basement and ground floor, still essentially retain the 12th-century appearance of the building.
Alterations were made in the 14th century and on a larger scale during the 15th century, when it belonged to the Bellomo family from which it derives its name. From this period, a number of details such as portals, mullioned windows and the staircase display influences from Catalan Gothic, a style which was popular on Sicily at the time (as Sicily was at the time part of the Crown of Aragon).
In the 18th century the palace and the neighbouring Parisio Palace were taken over by a Benedectine monastery who merged the buildings into one. In 1866 the palace was expropriated by the Italian state and serves as a museum since 1940. A renovation was carried out in 2004-2009.
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.
