In ancient times annexed to the Benedictine Abbey founded in 983, the church was reconstructed between 1476 and 1518.
The façade of the church, in terracotta, is crossed by an exquisite frieze, also in terracotta, composed of intertwined seascapes with winged satyrs realised around 1530.
The interior, divided into five naves, is rich in works made between 1400 and 1500 and is virtually an exhibition of the local artists of the time.
The six large terracotta statues leaning against the pillars of the central nave were sculpted by Begarelli and depict the Madonna of the Conception and the various saints.
Of particular importance is the ninth chapel in which the Apogee of Begarelli, the last work of the artist, is found, depicting the Madonna in Glory and the saints Peter, Paul, Geminiano and Benedict.
At the end of the right nave the Pietà can be admired.
Of particular value is the sacristy with the racks in splendid inlaid work carried out by Gianfrancesco da Cremona in 1548.
