The Cuba Palace in Palermo was built in 1180 by William II of Sicily in his great Royal Park, as his personal recreation pavilion, together with an artificial lake: it shows strong Fatimid art influences, as it was (at least partially) designed and decorated by Arab artists still living in Palermo after the Norman conquest in 1072. During the rule of Bourbon kings of Naples it was annexed to a barracks. In the 16th century it was turned into a lepers' colony.
The edifice has a rectangular plan, with massive forms. The four façades are marked by blind arcades, small windows, and niches. The name Cuba derives in fact from its approximately cubical form. The famous Italian Middle Ages author Boccaccio was impressed by the Cuba and set here one of the novellas included in the Decameron.
The Cubola or Little Cuba is another edifice built by William II for his park, in smaller dimensions. The most striking feature of the Cubola is the little hemi-spherical cupola.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
