Built in the 10th century and dedicated to
Prosper of Reggio, a bishop of the city, it was reconstructed by
Luca Corti and
Matteo Fiorentini between 1514 and 1523. The façade, with eleven statues of saints and patrones, was redesigned by
Giovan Battista Cattani in the mid-18th century. It includes a pleasant belfry/tower, begun in 1535 and never quite finished, with an octagonal plant. The interior of the church has a Latin cross plant, with three naves. The apse houses the splendid
fresco Last Judgement, by the
Bolognese artist
Camillo Procaccini. Also noteworthy are the wooden choir from 1546 and the
Assumption altarpiece by
Tommaso Laureti and
Ludovico Carracci (1602).
