It was established by Giuseppe Scandrolio, with support from key collaborators including Ercole Airoldi, Alfredo Gamassi, Umberto Baita, and Pierino Albini.

The presence of major international industries in the vicinity played a crucial role in financing these local sporting events.

In ten years these cyclists secured approximately 100 victories and numerous commendable placements in a variety of races.

Alfredo Bovet stood out as a prominent figure, achieving numerous successes such as winning the Milan San Remo in 1932, securing third place overall in the Giro d´Italia and claiming victory in the Tour of Catalonia in Spain.

[5] This era marked a distinguished period for the Castellanzese, with its athletes earning approximately 40 cups, plaques, and medallions of moral and intrinsic value.

The team was financed by Mr. Ferrario, a local wine merchant, and included notable players like Cesare Canavesi, Mario Rabolini, Giulio Selmo, and others.

[4][6] In 1970 the Unione Sportiva Castellanzese focused solely on registering with FIDAL (The Italian Athletics Federation) due to financial and other constraints.

The official song is sung by Max Corfini and Veronica Atzeni, and is a recording production by Roby Sky Travaini.

[15] The refrain goes: Nero verde è l'amore e la grande squadra va lotta sempre e vincerà, Nero verde è la fede ed il cuore mio ci crede e comunque vada sa che la Castellanzese griderà: alè ragazzi alè" Black green is love and the great team goes to always fight and win, Black green is faith and my heart believes it and whatever happens you know that Castellanzese will shout: alè guys, alè" Mascot The official mascot of USD Castellanzese is called "Backy", a silkworm wearing the team's official football shirt with the colors green and black, together with a football.

[16][17][18] In the 2013–2014 season, USD Castellanzese won the Prima Cartegoria with 22 victories, 4 draws and 4 defeats, achieving 70 points and a goal difference of +44.

Three seasons later in 2016–2017, the team won Promozione with 24 victories, 4 draws and 2 defeats, which resulted in 76 points with a goal difference of +44.

[22] The USD Castellanzese also owns "The Madonnina Sports Field" (in Italian: Campo Sportivo La Madonna), located in via Bellini, Castellanza, where both training sessions and youth matches take place.

It was renovated in 2001 when the field was equipped with synthetic grass and in 2014 a new turf, compliant with the regulations and requirements issued by the National Amateur League, with the presence of an irrigation system that allows the refrigeration of the soil.

[27] USD Catellanzese Neroverde initiative is a project to improve its youth team and expand regionally, giving players from other clubs the opportunity to be part of Castellanzese.

They do not wear the black and green uniform but are eligible for benefits guaranteed to the "Academies" in terms of technical support.

[28][29][30][31] In 2022, the Castellenzese club invited supporters to allocate their 5 per thousand calculated on 2021 IRPEF (in Italian: imposta sul reddito delle persone fisiche) income to the U.S.D.
