The church, already mentioned in 1186 in the will of a cleric, is of Romanesque origin and dedicated to Sant'Ambrogio, bishop of Milan. In the eighteenth century the construction of the apse, the four side chapels and the portico in front contributed to modifying its shape. Inside, the single nave has a vault of square stones that recall the Antelami technique. Important works preserved in the building are the scagliola high altar by Francesco Solari from 1757 and the early eighteenth-century high altarpiece depicting Saint Ambrose and the Virgin and Child.
