Oratory of ‘San Bernardino’. Built in honor of Bernardino da Siena, who often preached in the square in front of the Franciscan basilica, it was completed in 1452. It has a simple gabled structure with a twin portal and can be seen next to the church of San Francesco al Prato. The Oratory is known for the facade covered by the polychrome bas-reliefs of Agostino di Duccio, executed between 1457-1461 which make it one of the most significant examples of Renaissance art in Perugia.
