"It takes its name from the Mozzi family, one of the most important in Florence between the thirteenth and fourteenth centuries. The family of well-known papal bankers, lived in the Palazzo dei Mozzi, located at the bottom of the square, with a tower that still scrutinizes the traffic on the bridge.
Formerly called the Peace of San Gregorio, named after a small church incorporated today in the Museo Bardini. The name of "peace" referred to the ephemeral peace between Guelphs and Ghibellines of Cardinal Latino Orsini Malabranca. The palace of the Hubs had distinguished guests, like Pope Gregory X commemorated by a plaque on the wall of the Museo Bardini.
In addition to building its own museum, the antiquarian Stefano Bardini, bought in this square the same building of the hubs and the rear garden, which is clearly seen, with its flowered terraces on the hill, looking from the Ponte alle Grazie.
Other important buildings on the square are Nasi Palace, Baccio d'Agnolo, characterized by graffiti on the facade, and the great Palazzo Torrigiani-Del Nero, overlooking the Arno river: just to make the street along the river were sacrificed its gardens and picturesque crenellated wall. Nasi, a plaque commemorates the building of the social activity of the Marquis Carlo Torrigiani."
