Construction of the present Palazzo Reale began in 1618 for the Balbi family. From 1643-1655, work renewed under the direction of the architects Pier Francesco Cantone and Michele Moncino. In 1677, the palace was sold to the Durazzo Family, who enlarged the palace under the designs of Carlo Fontana.
In 1823, the palace was sold to the Royal House of Savoy. From 1919, the palace has belonged to the state.
The palace contains much original furniture and decoration. Frescoes inside include the Glory of the Balbi Family by Valerio Castello and Andrea Sghizzi, Spring changing slowly to Winter by Angelo Michele Colonna and Agostino Mitelli, and Jove establishes Justice on the Earth by Giovanni Battista Carlone. It also contains canvases by Bernardo Strozzi, il Grechetto, Giovanni Battista Gaulli, Domenico Fiasella as well as Bassano, Tintoretto, Luca Giordano, Anthony van Dyck, Ferdinand Voet, and Guercino. It contains statuary by Filippo Parodi.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
