At the southern end of Piazza Navona stands the Fontana del Moro, a striking fountain that draws the attention of many visitors. Although the overall design of the fountain is attributed to the famous artist Bernini, the main statue, known as the Moor, was sculpted by Giacomo della Porta.
Over time, the original figures surrounding the central statue were replaced. Today, the four other statues that circle the Moor are actually 19th-century copies of the originals, preserving the look and spirit of the fountain while protecting the historic artworks from further damage.
