The Royal Palace of Turin is a historic palace of the House of Savoy in the city of Turin in Northern Italy. It was originally built in the 16th century and was later modernized by Christine Marie of France in the 17th century, with designs by the Baroque architect Filippo Juvarra. The palace also includes the Palazzo Chiablese and the Chapel of the Holy Shroud, the latter of which was built to house the famous Shroud of Turin. In 1946, the building became the property of the state and was turned into a museum. In 1997, it was placed on the UNESCO World Heritage Site list along with 13 other residences of the House of Savoy.
