Overview

The old identification of Milan fans (since 1899) as popular and of Inter fans (since 1908) as aristocratic no longer makes sense, if it ever did, now that the majority owners of the two teams have long since left the city. The stadium, which the Municipality entrusted to a company shared by the two teams, remains under Milanese ownership. There is debate over whether to leave San Siro to build itself a new stadium, but the Superintendence of Archaeology, Fine Arts and Landscape, the fans and sports professionals have all opposed this, arguing "I don't understand why it should be knocked down...".

The stadium is the largest in Italy by capacity, with seventy-five thousand seats, arranged in three rings , starting from the original one inaugurated in 1926 and expanded at the end of the 1930s. The second ring, a single staircase higher than the previous one, was built in the 1950s: its reinforced concrete helical access ramps are still considered worth keeping by the competent authorities, due to their historical and architectural value. The outermost ring, with eleven towers and roofing beams that now unmistakeably identify the stadium from the outside, was added for the 1990 World Cup.

The San Siro Museum, with a collection of historical shirts, is the first stage of a guided tour that continues in the changing rooms, proceeds to the pitch and ends in the grandstand.
