Piazza San Carlo is a historic square in Turin, Italy. It is known for its elegance and architectural beauty, and is often referred to as the "living room" of Turin. The square is enclosed by two arcades of porticoes that house several cafés, shops, and restaurants.

At the center of the square is a statue of Emanuele Filiberto, Duke of Savoy, on horseback. The statue was erected in 1838 and is a popular meeting point for locals and tourists alike. On either side of the statue are two baroque churches - the Church of San Carlo and the Church of Santa Cristina.

Piazza San Carlo has a rich history and has been the site of many significant events throughout Turin's history. During the Risorgimento, it was the site of political rallies and demonstrations. It was also the site of a tragic event in 1933, when a bomb exploded during a political rally, killing 7 and injuring over 50.

Today, Piazza San Carlo is a popular destination for locals and tourists alike. The square is particularly beautiful at night when it is illuminated by the street lamps, creating a magical atmosphere. It is also the site of several annual events and festivals, including the Turin Book Fair and the Turin International Film Festival.
