The construction of the Castelbuono Castle began in 1316, by order of Count Francesco I of Ventimiglia, over the ruins of the ancient Byzantine town of Ypsigro, high on the San Pietro hill.
The castle mixes Arab-Norman features with others typical of the castles built during the Hohenstaufen rule of southern Italy: the cube shape recalls Arabic architecture; the square towers, although incorporated into those of the façade, reflect Norman architectural style, as also the battlements; and the round tower recalls aspects of Frederick II's times architecture.
The structure is on three floors, the first floor for the servants, with the essential services, the second for the nobility, with the sumptuous Cappella Palatina, and the third for the court and for guests.
The Cappella Palatina ('Palace Chapel') was built in 1683 by the brothers Giuseppe and Giacomo Serpotta, with a great profusion of precious marble, stuccowork, putti, and friezes that commemorate the most resplendent moments in the history of the House of Ventimiglia. Here is kept the holy relic of the skull of Saint Anne, in an urn that acts as the pedestal to the sculpted bust of Castelbuono's patron saint.
There are also the traditional underground dungeons and a tunnel that leads to the Church of San Francesco.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
