Given its beautiful Gothic structure and the fact that the Gonzagas decided to house their own tombs here until the age of the Renaissance, this place of worship bears tremendous significance. Unfortunately, it suffered devastating damage following violent bombing towards the end of the Second World War. Although it was rebuilt in the same style after the war, many of the precious works of art were lost, except for the magnificent chapel dedicated to St. Louis of Toulouse. The frescoes that still adorn its walls can be traced back to 1369 and have been attributed to the Modenese artist Serafino de' Serafini, who was strongly influenced by Tommaso da Modena. On the church's exterior, the portal, rose window and two high lancet windows are particularly striking.
