The Pantheon faces Piazza della Rotonda. The square is accented with the Fountain of the Pantheon. The fountain was created in 1575 at the bequest of Pope Gregory XIII. It was significantly modified in 1711. Sculptor Vincenzo Filippi created the marble dolphins and four grotesque masks at the base. In the center of Fontana del Pantheon is the 21 foot Macuteo Obelisk. It was uncovered at the Temple of Ra in Heliopolis near Cairo, Egypt. The obelisk dates back to the 12th century BC.
