Piazza San Carlo is one of the most beautiful squares of Turin, already parade and market square, it keeps the 17th century look of harmonious uniformity given to it by the royal architect Carlo di Castellamonte (1642-1650).
They have wisely transformed it in a fully pedestrian area ( well, bikes are accepted....)
The short side of the square, on the south-west side is fenced by the almost twin façades of the churches of Santa Cristina and of San Carlo.
