The so-called Medicean Breccia was largely employed by Cosimo I de’ Medici, lord of Firenze, who made this marble the symbol of his power. The Breccia di Seravezza was used in Firenze, mainly for coatings and interior decorations, in the Cattedrale di Santa Maria del Fiore, in Palazzo Pitti and in the Cappelle Medicee. It was also used for the construction of sculptures, like the two pyramids of Piazza S. Maria Novella, the Colonna di San Felice and the Fontana del Nettuno (by Bartolomeo Ammannati) in Piazza della Signoria.
