Palazzo Regio (Royal Palace), Cagliari

The Royal Palace of Cagliari, also known as the Viceregal Palace (Palazzo Regio), is a historic landmark in the Castello district, serving as the former residence of the viceroy during the Aragonese, Spanish, and Savoy dominations. Originally built in the 14th century, the palace became the official seat of the viceroy in 1337, under the orders of Peter IV of Aragon. Over the centuries, it underwent numerous modifications and expansions, adapting to the architectural styles and needs of each ruling power. Today, the Royal Palace houses the Prefecture of the Metropolitan City of Cagliari and the offices of the Province of Southern Sardinia, continuing its long tradition as an institutional and administrative center.

Architecturally, the Palazzo Regio reflects its rich history through various renovations, particularly those carried out during the 18th century by the Savoy dynasty. The Piedmontese engineers de Guibert and de Vincenti were responsible for the grand staircase leading to the main floor, while in 1735, the interiors were redesigned by Della Vallea, emphasizing elegant halls and refined decorations. The building’s west-facing façade, with its main portal and central balcony, was restored in 1769, as indicated by an inscription on the lunette above the French window.

One of the most significant periods in the palace's history was from 1799 to 1814, when the Savoy royal family took refuge in Cagliari, having fled Napoleon's invasion of Piedmont. The palace became their temporary residence, further reinforcing its political importance.

Inside, the Council Hall stands out for its exquisite decorations, completed during renovation works in 1885 when the building became the representative seat of the Province of Cagliari. The Perugian artist Domenico Bruschi painted the frescoes, while Angeletti worked on the stucco decorations, giving the hall a regal and sophisticated atmosphere. The palace's long façade, marked by monumental pilasters, faces Piazza Palazzo, while its high support arches extend along the rocky ridge overlooking the Villanova district.
