The Royal Palace is an impressive seventeenth-century building, which has been altered and extended on various occasions down the centuries. It still bears traces of the work of the most important artists active in Turin. Until 1865 it served as the residence of the Dukes of Savoy, the Kings of Sardinia and the Kings of Italy. It is possible to visit the royal apartments, lavishly decorated and furnished from the seventeenth to the twentieth century to the taste of the Savoy sovereigns. Clocks, porcelain, silver and furnishings, some dating back to the seventeenth century, can be seen.
