On the right-hand side, the first chapel has early Renaissance paintings of the life of St. Bernardino of Siena by Pinturicchio, painted c. 1480-1485. The story is that there was a feud between the clans of Bufalini of Città di Castello and Baglioni of Perugia, which the saint helped to pacify. In gratitude, Niccolò dei Bufalini commissioned the chapel soon after the saint's canonization in 1450.
