With its 75,817 seats, San Siro Stadium is the largest in Italy. Characterised by high standards of comfort and safety, it is classified in UEFA's Category 4. It has three rings and is divided into four sides: red, green, orange (the only one that does not have a third ring) and blue, the one traditionally reserved for the fans. It is in the second blue ring, in fact, that the Curva Sud is located. The four sides are also bordered by four corner towers, which soar above the stands reaching up to the roof. In addition to AC Milan and Inter matches, San Siro has also hosted several matches for the Italian national team and numerous international events, including two UEFA Champions League Finals (2001 and 2016).
