The statue of Cosimo I de' Medici stands in the middle of Knights' Square of Pisa, just in front of Palazzo della Carovana.
The Grand Duke Cosimo is represented in the robes of Grand Master, standing on a high pedestal, in the act of subduing a dolphin, symbol of his domination over the seas. The fountain, in front of the pedestal, was also erected by Francavilla. It has a basin in the form of a shell decorated with two grotesque monsters.
