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 Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
