Founded at the intersection of the three small villages that long after became Siena, this amazing square is the symbol in which the city is known in the cosmopolitan center, and one of the reasons why UNESCO recognizes the city and considers it the ideal embodiment of medieval cities. The square was originally built as a neutral ground for the three villages where holidays and political celebrations could be celebrated. The square extends over an area of 333 meters, and the square's design was supposed to resemble the folds of the abaya of the Virgin Mary. So it is zigzag. Today, the square has become a place where you can shop, eat Italian delicacies, and meet the people of the city.
