The Savoy dukes made this their seat from 1563, and three centuries of rule filled it with a Royal Armoury still ranked among Europe's finest collections of arms and armor. The palace's most startling space belongs to Guarino Guarini, whose black marble Chapel of the Holy Shroud spirals up into a dizzying honeycomb dome built to house the Shroud of Turin.
A fire gutted that dome in 1997, and the chapel reopened only in 2018 after twenty-one years of restoration, reached today directly from the palace's picture gallery. Behind the palace, the Giardini Reali were laid out to a design attributed to André Le Nôtre, the landscape architect of Versailles. Together with Turin's other Savoy residences, the palace anchors a UNESCO World Heritage Site inscribed in 1997.
