San Martino church, Minor basilica in Magenta, Italy.

San Martino is a Neo-Renaissance basilica begun in 1893 to designs by Alfonso Parrocchetti, with a wide central nave and two lower, narrower side aisles. It measures 87 metres in length, 30 metres across the transept, and its tiburio rises 57 metres. The facade, added between 1932 and 1959 by architect Mariani, carries reliefs of scenes from the life of Saint Martin, a central portal on four Corinthian columns, and statues of Saints Ambrose and Charles Borromeo above the side aisles.

Don Cesare Tragella proposed a new church for Magenta's growing population and to commemorate the fallen of the 4 June 1859 Battle of Magenta. Architect Alfonso Parrocchetti designed it in Neo-Renaissance style; the first stone was laid in 1893 and the structure was completed in 1901. Cardinal Andrea Carlo Ferrari consecrated it on 24 October 1903 but forbade moving the battle dead into the church. The bell tower was inaugurated in 1913, the facade finished in 1959, and Pius XII made it a minor basilica on 3 March 1948.

The church serves as an active place of worship for Magenta's community and hosts regular services following the Ambrosian Rite. This liturgical tradition connects the parish to the broader ecclesiastical heritage of the Milan region.

Visitors can reach the church on foot along Via Roma in central Magenta. The interior is open during scheduled service times.

The church was built to commemorate the 1859 Battle of Magenta, and the plan was to move the fallen soldiers' remains inside. Cardinal Andrea Carlo Ferrari, who consecrated it in 1903, forbade the transfer, so one of the two founding purposes was never fulfilled.
