The Zisa is a castle in the western part of Palermo. It is included in the UNESCO Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale World Heritage Site.
The construction was begun in the 12th century by Arabian craftsmen for king William I of Sicily , and completed by his son William II. The edifice had been conceived as summer residence for the Norman kings, as a part of the large hunting resort known as Genoardo. that included also the Cuba Sottana, the Cuba Soprana and the Uscibene palace.
The Zisa is clearly inspired by Moorish architecture. The name Zisa itself derives from the Arab term al-Azīz, meaning 'dear' or 'splendid'. The same word, in Naskh script, is impressed in the entrance, according to the usual habit for the main Islamic edifices of the time.
In the 14th century merlons were added, by partly destroying the Arab inscription (in Kufic characters) which embellished the upper part of the edifice. More substantial modifications were introduced in the 17th century, when the Zisa, reduced to very poor conditions, was purchased by Giovanni di Sandoval e Platamone. The latter's marble coat of arms with two lions can be seen over the entrance fornix. Several rooms of the interior were modified and others added on the ceiling, a great stair was built, as well as new external windows.
From 1808 to the 1950s the building was used a residence by the princes Notarbartolo di Sciara. Acquired by the Region of Sicilia it was restored in the 1990s. The Zisa today is opened to tourists. Some rooms house Islamic art pieces, tools and artifacts from the Mediterranean area. The most notable room is the central hall, with a mosaic decoration; once it had a fountain too, from which the water flowed outside.
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.
