Palazzo Spini Ferroni is a large Gothic palace located along Via de' Tornabuoni at the corner of Piazza Santa Trinita, in central Florence, Tuscany, Italy.
The palace was commissioned in 1289 by the rich cloth merchant and banker Geri Spini, on plots that he had bought after the 1288 flood of the river Arno, from the monks of Santa Trinita.
Built during a turbulent medieval century in the city, noted for internecine conflict between families, the palace is a fortress-like stone block, with street level arches in a tall first story, with a protruding cornice surmounted by merlons.
In the 1670s, Marquis Francesco Antonio Ferroni, a member of Grand Duke Cosimo III's ruling circle, had it redecorated with stuccoes by Giovanni Battista Foggini and Lorenzo Merlini.
In 1874, it was partly renovated in neo-medieval style; shop-fronts were opened in the ground floor and a tower and an arch facing the river Arno were demolished, giving the palace the present appearance.
