Transept
On the right transept is altar dedicated to Blessed Ambrogio Sansedoni, also portrayed in a canvas by Francesco Rustici (1611-612).
Notable amongst the chapels are the second, entitled to the martyrs of the German Nation, and the third, which includes a Madonna with Child and the Saint Jerome and John the Baptist by Matteo di Giovanni.
The fourth chapel has a Baroque canvas by Raffaello Vanni (1649) and a St. Anthony the Abbot from 1426. The Majesty by Guido da Siena (dated to 1221, but probably from 1265-1270 ad with additions by a Duccio's follower) is in the centre of the fifth chapel, where are also works by Matteo di Giovanni, Benvenuto di Giovanni and two frescoes by Giuseppe Nicola Nasini. The left transept ends with the altar of St. Dominic.
