Located at No. 13 on central Via Cavour, the building originally known as Palazzo Piossasco di Rivalta dates back to the 17th century. It is situated on the corner of a lot bordered by the districts of Arcivescovado and Madonna degli Angeli. In the late 18th century, the palace became the property of Marquis Maurizio Luserna Rorengo di Rorà, who acquired it as an alternative residence to the family palace in Bene Vagienna, in the province of Cuneo. Its current appearance is the result of modernization carried out between 1779 and 1781 by Benedetto Alfieri. Alfieri reworked the Baroque elements typical of Guarini, aligning them with the classicism of Juvarra, his predecessor as court architect, thus giving the palace its present form. The palace later became the residence of Marquis Emanuele Luserna di Rorà, who served as mayor of Turin from 1862 to 1865. During his tenure, in 1864, Turin lost its status as the capital of Italy to Florence. However, Emanuele oversaw significant urban and industrial development in the city. In 2017, the Buratti-Lera family, owners of the adjacent Grand Hotel Sitea, acquired the main floor of the palace. After a meticulous two-year renovation, they converted it into the current Royal Palace, which features six suites, a wellness area, and a dedicated butler trained at TIBA | The International Butler Academy
