The church, mentioned as early as 1186 in the last will and testament of a cleric, is of Romanesque origin and is dedicated to Sant'Ambrogio, bishop of Milan. In the eighteenth century the construction of the apse, the four side chapels and the front porch changed its appearance. Inside, the single nave has a vault of square stones reminiscent of the Antelami technique. Important works preserved in the building include: the high altar in scagliola by Francesco Solari, 1757, and the altarpiece of the high altar from the early eighteenth century depicting Saint Ambrose and the Virgin with Child.
