Inside the fascinating gothic style ground floor, you'll find the altar with the marble group of 'Sant'Anna, the Madonna and Child' by Francesco da Sangallo (around 1526). Next to it is the tabernacle built by Andrea Orcagna between 1349 and 1359 to house the Virgin with Child and Angels, painted by Bernardo Daddi from 1347. The work replaced a miraculous image of the Madonna di Orsanmichele (by Ugolino di Nerio) that was probably lost in the fire of 1304.
Many frescoes from the late fourteenth century adorn the columns, and the vaults are completely frescoed with characters from the Old and New Testament.
Going up to the first floor by passing through the palazzo dell'arte della lana, you find the large statues that were once preserved in the external niches and which have all been restored, including some Renaissance masterpieces commissioned by the various Florentine Arts, such as Donatello's Saint Mark, the Doubting Saint Thomas by Verrocchio, together with Ghiberti's Saint John the Baptist and Nanni di Banco's Sant'Eligio and San Filippo.
We also must mention the sculptures of San Jacopo, San Pietro and the Madonna della Rosa attributed to Niccolò di Pietro Lamberti, Bernardo Ciuffagni and Pietro di Giovanni Tedesco respectively.
The second and last floor is accessed by a spiral staircase. Here, the museum showcases forty small stone sculptures depicting saints and prophets that were originally placed on the top of the outside columns that have three-mullioned windows and two portals.
Through the large windows, you can admire an incredible view of Florence.
