Founded by Gundiperga, the wife of king Rotari (636-652), the church of Saint Giovanni Domnarum, or “delle Signore” (of the ladies) refers to the presence inside the church of a baptismal font reserved for women.

The best-preserved part of the church is the crypt, where we can still see the side of the Corinthian capitals from the late antiquity and others from the thirteenth century with leaves on the corners. The frescoes date from the twelfth century.
