Francesco di Giorgio
The counterfaçade houses the remains of two 14th century sepulchres, as well as two large fragmentary frescoes from the city gates of Porta Romana and Porta Pispini: a "Coronation of the Virgin" by Sassetta and Sano di Pietro (1447–1450) and a "Nativity" by Il Sodoma (1531). Also visible is the ancient 15th century portal by Francesco di Giorgio Martini.
