St. Peter's Square is located directly in front of St. Peter's Basilica. Laid out in the 17th century, it is a gathering place for Christians. Standing in this grand square, even if you are not a christian it's hard not to be awestruck by its grandeur. Many sculptures, all of religious figures, stand atop a colonnade surrounding the square, which was completed by Gian Lorenzo Bernini and his students. At the center of the square stands an obelisk that originally stood at Heliopolis, but was later ordered to be brought to Rome by the emperor Caligula. At the top of the obelisk there was once a gilt ball that was said to contain the ashes of Julius Caesar.
