San Siro (Lombard: San Sir) is a vast district ("quartiere") of Milan, Italy, part of the Zone 7 administrative division of the city. About 5 km north-west of the city centre, it borders the districts of Lampugnano, QT8, FieraMilano, and Trenno.

History

Until the 19th century, San Siro was a small settlement, on the banks of the Olona river; its centre was in the surroundings of what is now Piazzale Lotto.^{[citation needed]} The area has been radically transformed in the 20th century.^{[citation needed]}

San Siro is a very diverse district, with wide green areas and cemented neighbourhoods, low-income and high-income housing, villas and apartment blocks.^{[citation needed]} Most of the buildings in the area date back to the mid 20th century.^{[citation needed]}

The district is also characterized by prominent sports structures, most notably the Giuseppe Meazza football stadium, home of A.C. Milan and Inter Milan. It also houses the most important Milanese hippodrome, as well as other horse racing-related structures. The Palasport di San Siro arena, mainly used for basketball and volleyball games, was also in this district; it was closed in 1985 when its roof collapsed after a large snowfall.
