Named for the Bishop of Milan, this 10th-century church once belonged to an order of Benedictine nuns. Just this side of austere, the church is one of the oldest in Florence. Though its facade is 19th-century, inside are 15th-century panel paintings and a lovely but rather damaged 1486 fresco by Cosimo Roselli, in the chapel to the left of the high altar. The tabernacle of the Blessed Sacrament was carved by Mino da Fiesole, who, like Verrocchio, il Cronaca, and Francesco Granacci (1469/77–1543), is buried here.
