Saint Ambrose (Italian: Chiesetta di Sant'Ambrogio) is a small church which is an annex to the farmhouse that takes its name from it, in Brugherio, Italy.

According to oral[1] and literary sources, in the fourth century, where the church and its farm are now located, there was a villa[2] belonging to the Bishop of Milan, Ambrose.

[3] Ambrose gave his sister a part of the relics of the three Magi who had been brought to Milan as a gift from the Holy Roman Emperor Frederick I to Bishop Eustorgio.

They depict Saint Ambrose among his brothers Satyr and Marcellina with the holy martyrs Sebastian and Pope Fabian.

On October 31,[18] Monsignor Ennio Bernasconi, mitred abbot of St. Ambrose of Milan, praised not only Marcellina and his brothers but also the owners responsible for the restoration.

[16] It was rebuilt in brick[22] in the style of Lombardy,[23] in reference to the Basilica of Saint Ambrose in Milan, and is divided by a cornice.

[15][23]The church is characterized by a small nave with apse,[24] covered by a gable in turn supported by wooden trusses with decorated warping.

[15] The flooring is made of terracotta brick, while the walls are painted in a light colored parchment, itself decorated with polychrome socket boxes.
