 The earthquake of 1780 damaged the church, and it was rebuilt by the architect Angelo Venturoli.Over the entry is the heraldic shield of the Ghisilieri family, and the bell-tower was adapted from a medieval tower from a family palace.The simple exterior does not reflect the highly decorated interior, which has ceiling frescoes by Luigi Samoggia and Alessandro Guardassoni (1868), a main altarpiece is a "St Gregory shows the bleeding Eucharist to the Heretic" by Denys Calvaert (1581) and works by Camillo Procaccini.
