The church was connected with the adjacent monastery of the Jesuits: built in 1602 and consecrated in 1628. It features an unfinished façade with a classical structure that rhythmically presents four large marble fluted pilasters and, at the center, a Palladian window. The interior, with a single nave, with side-chapels and barrel–vaults, is richly decorated with altars, plaster friezes, paintings and sculptures which constitute the most important testimony to the Baroque style in Cremona. Notable features are: on the third right hand altar a canvas with San Giuseppe e il bambino Gesù by A. Massarotti, in the presbytery the monumental altarpiece in carved wood, attributed to G. Bertesi, holding the canvas San Marcellino battezza la figlia del carceriere by G. Gatti (1604) and at the sides of the main altar the two canvases by a. Massarotti San Marcellino e San Pietro volano in soccorso dei cremonesi in battaglia contro i milanesi and Il trasporto delle reliquie di San Marcellino e San Pietro; on the last left-hand altar, dedicated to the Virgin Mary, a baroque wooden statue with on either side two episodes from the life of Sant’Orsola painted by Luigi Miradori known as Il Genovesino and, further to the left, the Presentazione di Maria al tempio by the same artist.
