Fontana del Nettuno

Lonely Planet review

Adjacent to Piazza Maggiore, Piazza del Nettuno owes its name to this explicit bronze statue sculpted by Giambologna in 1566. Beneath the muscled sea god, four cherubs represent the winds, and four buxom sirens, water spouting from every nipple, symbolise the four known continents of the pre-Oceania world.
