This building, beside the (no longer existing) New Bridge, in the Middle Ages (12th -14th century) was the home of the Bocci family. Previously it had a large colonnaded portico (traces still visible) along the outside walls. Worthy of note are the four-part mullions in marble with later rectangular windows inserted, visible on via Trento. The building was renovated in the 16th century and was lived in by the widows of the Medici family, who had access to the Royal Palace through an overhead covered passage, still present, at the end of via S. Maria.
