Piazza San Carlo is one of the main city squares in Turin, it is said to be the most beautiful square of the city and preserves the peaceful and uniform seventeenth-century look given by the royal architect Carlo di Castellamonte (1642-1650). In the center, you can see the equestrian statue of Emanuele Filiberto, represented by Carlo Marocchetti (1838) in the act of sheathing the sword after the battle of San Quintino in 1557; that's one of the most significant statues of the early nineteenth century (nicknamed El Caval d’brons). The twin churches of Santa Cristina and San Carlo Borromeo close the southern end of the square. It was laid out in the 16th and 17th century and is an example of Baroque style. Its current name is an hommage to Charles Borromeo while the square was previously known as Piazza Reale, Piazza d'Armi, and Place Napoleon. The square has become a normal stage of different historical and social events, including election rallies, concerts, events, live TV.
