The Church of San Martino or 'della Disciplina'in Tregnago, an ancient parish church in the Calavena area, probably dates back to the 7th-8th century, as evidenced by the fact that it is named in honour of Saint Martin, of Frankish origin. After operating as a parish church for several centuries, it was the seat of many religious confraternities in the late Middle Ages and in modern times. Currently used for secondary functions, its architecture features Romanesque stylings, with a single nave inside. In the small apse chapel built in the 15th century by the Casari family, there are frescoes by Niccolò Golfino depicting Our Lady of Graces with the 'Disciplinati' (flagellants) and Saints Apollonia and Agatha.
