Francesco di Giorgio
Built in the shape of a Greek cross, it has a cupola with a cylindrical tambor. The design is attributed to Francesco di Giorgio Martini. Most of the brick façade has only a sliver of a cornice with architrave in travertine marble, added in 1545–1550. The interior was frescoed in the 16th century by Giovanni Paolo Pisani, Raffaello Vanni, and Astolfo Petrazzi. The main altarpiece is a bas-relief in stucco and terracotta depicting the venerated "Madonna della Selva", and is attributed to Francesco di Giorgio Martini.
