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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
