Obelisk of Caligula
The Vatican Obelisk, also known as the Obelisk of Caligula, is a monumental Egyptian monolith of red granite that marks the center of St. Peter's Square. Originally erected in Heliopolis for an unknown pharaoh, it was brought to Rome in 37 AD by Emperor Caligula to adorn the spina of the Circus of Nero. Unlike most other obelisks in Rome, it remained standing throughout the Middle Ages at its original site near the Old St. Peter's Basilica. In 1586, Pope Sixtus V commissioned the architect Domenico Fontana to relocate the obelisk to its present position, a massive engineering feat involving 800 workers and 75 horses. The obelisk is unique among Rome's major obelisks for having no hieroglyphics and is topped by a bronze cross containing a relic of the True Cross. Today, it functions as a monumental sundial, with its shadow crossing zodiac signs embedded in the square's pavement.
