Palazzo Regio

The Palazzo Regio, also known as Viceregio, is a historic building in Cagliari, the ancient residence of the representative of the king of Sardinia during the Aragonese, Spanish and Savoy domination and now the seat of the Metropolitan City of Cagliari. It is located in the historical Castello district.

The building had been originally built in the 14th century and became the seat of the viceroy since 1337, at the behest of Peter IV of Aragon. Over the centuries the building underwent several modifications and extensions. Particularly significant were the 18th century restorations; in 1730, at the hands of the Piedmontese engineers de Guibert and de Vincenti it was built the grand staircase leading to the main floor, the rooms of which were restored in 1735 by della Vallea. The west facade, with the main portal in line with the staircase, was arranged by 1769, as evidenced by the inscription on the window bezel door that opens onto the central balcony.
