The parish church of S. Martino was built in the 17th century on a pre-existing Romanesque building recognisable by the arches on the right side of the chapel of the Crucifix. The bell tower is also Romanesque, with three lancet windows on the top floor whose columns have capitals decorated with animals, heads, cords and palms.
Inside, there are numerous canvases on the walls. The altars and the choir are richly decorated with polychrome stuccoes, some of which by Carlo Terugia (1654). The high altar is in gilded wood and painted in faux marble (18th century). The brass lamp pierced in front of the altar was donated, as tradition says, by St. Charles Borromeo. Interesting, in the sacristy, three walnut wardrobes with twisted columns of the seventeenth century.
The church was restored in 1984-91. Excavations have shown part of the ancient apse (8th-9th century). Fragments of polychrome stucco from the 12th-13th centuries have been discovered in the choir and parts of late 15th century frescoes have been found on the walls of the nave.
