A masterpiece of the Renaissance and a true jewel of the Cathedral, the Sacristy of the Cathedral has its walls internally decorated with wooden marquetry reproducing the great innovation of the fifteenth century in Florence.

Within the Sacristy of the Masses, or of the Servites, there are wooden inlays with a strong perspective and illusionistic value. They were designed, on the front side, by Alesso Baldovinetti, Maso Finiguerra and Antonio del Pollaiolo and set up by Giuliano and Benedetto da Maiano. They are among the first manifestations in Italy of this technique, linked to studies on perspective. The decoration is imported on two registers crowned by a frieze of putti and festoons sculpted in the round. In the central panel we see Saint Zanobi and his disciples Eugenio and Crescenzio, between characters and facts of the Old Testament. The marble sink, with two cherubs sitting on a skin is by Buggiano and is twin to the one in the sacristy of the Canons. The other, with an angel’s head, is by Mino da Fiesole. It is in this Sacristy that Lorenzo The Magnificent found escape from the Pazzi conspiracy on April 26, 1478. The twelve bronze panels of the doors of this Sacristy, with compartments with The Madonna and Child, St. John, Evangelists and Doctors of the Church among angels , were made by Luca della Robbia (with the collaboration of Michelozzo and Maso di Bartolomeo), author of the polychrome terracotta lunette with the Resurrection.
