St. Peter's Square, one of the most beautiful and famous in the world, is surrounded by Bernini's imposing colonnade that seems to "embrace" it with its 284 columns (1656-67). In the center stands a 26-meter tall Egyptian obelisk from Heliopolis; at its sides two beautiful fountains by Maderno and D. Fontana; everything is grandiose and at the same time extremely harmonious. In the background, the massive structure of the Basilica with its gigantic façade (114 meters by 45). From the year 1452, when B. Rossellino undertook the construction, many architects among the most illustrious of their times contributed to make the new temple of Christianity the most majestic in the world: Bramante, Giuliano da Sangallo, Raphael, Antonio da Sangallo the Younger, Michelangelo, Pirro Ligorio, Vignola, Della Porta, D. Fontana and Maderno. The new St. Peter's Church was consecrated by Pope Urban VIII in 1626. The vestibule introduces to the 5 bronze doors: the last one to the right is the Holy Door, and it is only opened in occasion of Jubilees.
