The Oratory of Sant’Ilario can be reached from the portico of the building of the Ospedale Vecchio in Via D’Azeglio. Built in 1663 and divided into three small naves with pillared columns with stucco. The lunettes shown with fruit, floral decorations and figures of the Saints and blessed citizens, are the work of Giovanni Maria Conti della Camera. Close to the altar is the tomb of the founder of the Hospital della Misericordia, Rodolfo Tanzi.
