Finally it snowed in Turin and the great cold is come so quickly. If you are planning to visit the city in January, this is definitely the right period of the time.
All around the center, especially in the main squares, such as Piazza San Carlo, Piazza Solferino and Piazza Castello, there are still the Christmas open market, having all the seasonal food and beverages, souvenirs and, of course, Christmas staff.
Feel free to shop and sneak around, finding something interesting for sure.
