San Siro’s history explained

The founding years (1925–1947)

Built by industrialist Piero Pirelli exclusively for AC Milan, San Siro opened as a football-only stadium, unusual for Italy at the time. Its early design reflected English-style arenas, shaping Milan’s growing football culture.

The shared era begins (1947–1954)

After World War II, Inter Milan moved in, transforming San Siro into a symbol of coexistence and rivalry. Sharing one stadium intensified the Derby della Madonnina, one of football’s fiercest derbies.

Expansion & modernization (1955–1986)

A second tier dramatically increased capacity, turning San Siro into one of Europe’s largest stadiums. It became a regular host for international fixtures and major club competitions.

Italia ’90 transformation (1987–1990)

Ahead of the 1990 FIFA World Cup, a third tier, eleven cylindrical towers, and the now-iconic spiral ramps were added. The renovation gave San Siro its distinctive modern silhouette.

European glory & global fame (1990s–2010s)

San Siro witnessed Champions League triumphs for both Milan clubs. Its atmosphere earned a reputation as one of football’s most intimidating stages.

The future debate (2020–present)

With modernization challenges and redevelopment plans under discussion, San Siro stands at a crossroads, balancing heritage preservation with contemporary stadium demands.

Construction and architecture of San Siro

Designed by architect Ulisse Stacchini (also known for Milan Central Station), San Siro was originally built using reinforced concrete, a modern material at the time.

The 1990 renovation introduced:

  • 🏗️ Eleven cylindrical red towers supporting the third tier
  • 🌀 Iconic spiral ramps allowing smooth crowd flow
  • 🏟️ A partially covered roof structure supported by girders

Unlike multi-sport Italian stadiums of the early 20th century, San Siro was purpose-built for football, ensuring closer sightlines and a more immersive spectator experience.

Today, San Siro remains one of Europe’s most historic football venues, with a capacity of over 75,000. Managed by the Municipality of Milan, it continues to host Serie A matches, international fixtures, concerts, and major events.
