The Chapel of the Crucifixion or the Cybo-Soderini Chapel was remodelled in the Baroque era when a Flemish artist, Pieter van Lint executed its cycle of frescos on the vault and the lunettes which depict "Angels with the Symbols of the Passion" and "Prophets". Two big frescos on the side walls show scenes from "The Legend of the True Cross". There is a 15th-century wooden crucifix above the main altar in a Corinthian aedicule. The chapel was restored by Lorenzo Soderini in 1825.
