This is the central figure of the Fontana del Nettuno (Fountain of Neptune) in Rome, Italy, located at the north end of the Piazza Navona. It was once called "Fontana dei Calderari" because it was located close to a small alley with blacksmith's workshops, makers of pots and pans and of other metal based businesses, all of them generating heat. The fountain as it exists today was finally completed in 1878 by Antonio della Bitta, who added the imposing sculpture of "Neptune fighting with an octopus".
