The apse has an aged fresco depicting Christ Pantocrator attributed to Bernardino Grossi and his son in law Jacopo Loschi.

The Oratorio della Concezione (Oratory of the Immaculate Conception) was built as a chapel annexed to the church.

It was designed by Bernardino Zaccagni and Giovanni Francesco Ferrari d'Agrate in the 16th century.

In 1816, the painting was restored, but is now displayed in the Galleria Nazionale di Parma.

Cells were in the nave, and this led to a replacement of the windows, and covering of the frescos.
