The club was founded in 2008 as
F.C. Castiglione Savoia A.S.D., after the merger of
Nuova A.C. Marmirolo (with the transfer of its sports title of
Eccellenza) of
Marmirolo and the local team of
A.S.D. Savoia from
Terza Categoria Mantova. In the 2009–10 season the club was promoted from the
Eccellenza Lombardy to the
Serie D. In the summer of 2010 the club changed its name to "F.C. Sterilgarda Castiglione A.S.D.", after the name of their main sponsor,
Sterilgarda Foods S.p.A., known dairy company. In the
2011–12 Serie D season, Sterilgarda Castiglione was promoted to
Lega Pro Seconda Divisione for the first time. The sponsor, anyway, withdrew its support and the club changed its name to the current one. After two seasons it was relegated back to Serie D, where in 2014–15 it won group B but later announced that it definitely renounced promotion because of economic problems to focus on youth football. However, the senior team entered
Terza Categoria Bresciana for the 2015–16 season. After a few years of settlement, the club has risen to
Eccellenza Lombardy, the regional
Eccellenza football division for clubs in Lombardy, Italy. == Colors and badge ==
