Domenico Fontana
On December 9, 1586 (the year when Domenico Fontana erected in Saint Peter's Square the obelisk once standing in the Circus of Nero), Pope Sixtus V declared Borgo the fourteenth Rione of the city. Its coat of arms represents a Lion (representing the Leonine City), and three Mounts and a Star (taken from the coat of arms of Pope Sixtus).
