The Palazzo di Reale, or Royal Palace of Turin, was originally the Bishops Palace in old Turin, when the city became the capital of Savoy. It was taken over by Duke Emmanuel Philbert and became his residence until his death in 1580, at which point his son, Charles Emmanuel I moved in.
Though already large and opulent, the Palace grew in magnificence following the marriage of Charles Emmanuel's son, Victor Amadeus, to French Princess Christine Marie. She is responsible for modernizing the palace to 17th century standards, employing renowned architect Filippo Juvarra. The most famous of his additions is Scala delle Forbici, a magnificient staircase. Christine Marie eventually moved into a different palace, la Palazza Madama, also rebuilt by Juvarra.
Today, the palace is a premier example of classic European aristocracy. It houses a museum dedicated to the House of Savoy, and its armory is a point of interest, as it contains a wide variety of historical arms and armor.
