The left hand pier altar has a fine 15th century marble tabernacle in the form of a pedimented aedicule, with the actual home for the Blessed Sacrament being venerated by a four standing angels. The door is in gilded bronze, with a relief of Jesus the Nazarene with his cross and column of flagellation. The Grotesque relief detailing is gilded. The work is ascribed to Luigi Capponi or Antonio Bregno. This tabernacle was re-located here in the early 17th century, and provided with flanking frescoes of SS Peter and Paul. God the Father is depicted above.
