The church of San Michele Arcangelo is the parish church of Truccazzano, in the metropolitan city and archdiocese of Milan; it is part of the deanery of Melzo. The Liber Notitiae Sanctorum Mediolani states that the original church of Truccazzano was a branch of the parish church of Corneliano. In 1398, Truccazzano is mentioned as a chapel dependent on the parish church of Corneliano, and in 1564 as a rectory. A description of this church is contained in the report of Leonetto Clivone's visit in 1570. Between the 18th and 19th centuries, the church underwent several decorative and enlargement projects: two side chapels were built, the high altar, designed by Francesco Rossi in 1812, was created, and the pronaos was constructed.
