Santi Pietro e Paolo d’Agrò church one of the foremost examples on Sicily of Norman architecture. The church was constructed during the 12th century as part of a Basilian monastery. Its exterior is characterised by its block-like form, but the facade is richly decorated. Inside, the church has the plan of a basilica with three aisles. Two domes rise from the central nave, one above its centre and one above the choir.
The architecture of the church displays influences from a vast variety of sources, and constitutes heritage of Muslims, Byzantines, and Normans. The block-like form of the exterior is reminiscent of North African contemporary architecture while the floor plan of the church is similar to the way churches were built in the Byzantine architectural tradition. Its principle of construction at the same time is essentially that of Western European Gothic architecture. In its details and decorations, too, the church exhibits a wealth of influences (e.g. in the use of muqarnas vaulting).
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.
