Il Pertini, Public library and national heritage site in Cinisello Balsamo, Italy.

Il Pertini is a public library in Cinisello Balsamo built across four floors with a contemporary design that houses reading spaces, study areas, and multimedia collections. The entire building is accessible without stairs or barriers, making it easy for everyone to move through and use the resources available.

Cinisello's first public library opened in 1921 on the ground floor of the town hall, affiliated with the Provincial Union of Popular Libraries. In 1970 the municipality set up a proper municipal library with branches in Balsamo and Cinisello, unified in 1975 as the Civic Library in the northern wing of Villa Ghirlanda Silva, bought the year before. Il Pertini was inaugurated on 21 September 2012, built on the perimeter of the Cadorna school, whose facade was kept.

The building preserves the facade of the Cadorna school, the first elementary school in Cinisello Balsamo. A gold record donated by rapper Vegas Jones for his album Bellaria is displayed on the first floor. The web radio and TV "Il Pertini Radio", launched in 2021, is run by young people from the area.

The building is on the perimeter of the former Cadorna school, whose facade was kept. The 5,000 m² public area spans four floors, with a study room, three workshop rooms, a 176-seat auditorium and a meeting room. Free Wi-Fi and library PCs are available; digital resources are reachable through MediaLibraryOnline.

The library operates branch lending points called FuoriPertini scattered across different neighborhoods of the city. This approach brings services closer to residents who might not otherwise visit the main building.
