[4] Remnants of the medieval borgo in modern Affori include a watchtower (located in Via Osculati and dating back to the 14th century).

As a consequence, the development of Affori was slower than that of the surrounding settlements that were closer to, or traversed by, these main roads.

Bresso regained its autonomy in 1884, but Bruzzano and Dergano remained part of the comune, which would eventually be renamed just "Affori" (in 1912).

The next most important monument is the church of Santa Giustina; it houses a painting, credited to Ambrogio de Predis, that has raised the interest of art scholars because of its similarity to Leonardo da Vinci's Virgin of the Rocks.

Other places of interest in Affori include the Paolo Pini Art Gallery (established in 1995), which has paintings by contemporary artists such as Enrico Baj, Günter Brus, Martin Disler, Piero Gilardi, Giuseppe Maraniello, Klaus Karl Mehrkens, Aldo Spoldi, Emilio Tadini, and Bernd Zimmer, and the Affori Library, a large public library which is best known for its corpus of children literature and comics.

Affori hosts the prominent historic community band of the Milanese area, the "Corpo Musicale Gaetano Donizetti", established in 1853 and still in activity.
