The chapel of the Madonna delle Grazie located inside the ring walls is a evidence of medieval architecture, precious for its historic and artistic interest.
It is a small building placed against the bell tower and not visible from the outside.
The southern face keeps large frescoes’ fragments portraying St. Christopher (credited to James from Ivrea), and the Lady of the milk with her baby.
The interior consists of a single nave and a presbytery, which was restored in XX century.
The larger fresco describes the Stories of Saints: on the left is St. Margareth praying with a Dragon; at the center Santa Liberata – patroness of birth and children – with her babies Saint Gervasio and Saint Protasio; on the right we find Saint Lucia.
Further investigations are in progress, in order to recover the rest of the iconographic traces.
