On the harmonious square to which it has given its name, the cathedral is adorned with an attractive Renaissance portico, a rose window and a mosaic from the 13C. Inside, there is an attractive altar cross painted on parchment applied to a plank by Alberto Sozio, frescoes by Pinturicchio and the funerary monument of Fra Filippo Lippi. Finally, in the apse, there are frescoes in which Lippi depicted the life of the Virgin, placing her in the scene dressed in Dominican attire.
