The Bardi Chapel, the second chapel on the right of the apse, was founded by Riccardo Bardi and dates from early 14th century. The high-relief on a pillar on the right depicts "St Gregory blessing Riccardo Bardi". The walls show us some early 14th-century frescoes attributed to Spinello Aretino. The "Madonna del Rosario" on the altar is by Giorgio Vasari (1568)  The sacristy, at the end of the left aisle, was built as the Chapel of the Annunciation by the Cavalcanti family in 1380. It houses, after a recent period of fourteen years of cleaning and renovation, the enormous painted "Crucifix with the Madonna and John the Evangelist", an early work by Giotto. The sacristy is also embellished by a glazed terra cotta and a marble font, masterpieces by Giovanni della Robbia (1498). The cupboards were designed by Bernardo Buontalenti in 1593. The paintings on the wall are ascribed to Giorgio Vasari and to other contemporary Florentine painters. The large Gothic window with three mullions at the back wall dates from 1386 and was based on cartoons by Niccolò di Pietro Gerini  The Spanish Chapel (or "Cappellone degli Spagnoli") is the former chapter house of the convent. It is situated at the north side of the green Cloister ("Chiostro Verde"). It was commissioned by Buonamico (Mico) Guidalotti as his funerary chapel. Construction started c. 1343 and was finished in 1355. The Guidalotti chapel was later called "Spanish Chapel", because Cosimo I assigned it to Eleonora of Toledo and her Spanish retinue. Within the Spanish Chapel there is a smaller Chapel of the Most Holy Sacrament. The Spanish Chapel was decorated from 1365 to 1367 by Andrea di Bonaiuto, also known as Andrea da Firenze. The large fresco on the right wall depicts an "Allegory of the Active and Triumphant Church and of the Dominican order". It is especially interesting because in the background it shows a large pink building that some think may provide some insight into the original designs for Florence Cathedral by Arnolfo di Cambio (before Brunelleschi's dome was built). However, such an interpretation is fantasy since the Duomo was never intended to be pink, nor to have the belltower at the rear.
