Detail of the grand east facade of St Peter's Basilica, 116 m wide and 53 m high. Built from 1608 to 1614, it was designed by Carlo Modeno. The central balcony is called the Loggia of the Blessings and is used for the announcement of the new pope with "Habemus Papum" and his Urbi et Orbi blessing. The relief under the balcony, by Buonvicino, shows Christ giving the keys to St. Peter. The facade is topped by 13 statues of apostles in travertine. The dome was designed by Michelangelo and completed in 1593.
