Numerous and prestigious are the sacred furnishings of the church, including the bronze crucifix found on the main altar, and the angel candleholders placed at the ends of the rich marble transenna, made by Giambologna, as well as the large ciborium in silver designed by Giovanni Battista Foggini (1678–86) on the altar of the Blessed Sacrament chapel. On the numerous side altars are located 16th and 17th century paintings. Among these works are the "Our Lady of Graces with saints", by the Florentine Mannerist Andrea del Sarto, and the "Madonna enthroned with saints" in the right transept, by Perin del Vaga, a student of Raphael, both finished by Giovanni Antonio Sogliani. In the Baroque style are: the "Disputa del Sacramento" by the Sienese painter Francesco Vanni, and the "Cross with saints" by Genoan Giovanni Battista Paggi. Particularly well-loved is the 13th century image of the "Madonna col Bambino", also called the "Madonna under the organ", attributed to Berlinghiero Berlinghieri of Volterra.
