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:The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
