St. Peter's BasilicaPiazza San Pietro, 00120 Città del Vaticano, Vatican City
The Papal Basilica of St. Peter in the Vatican, or simply St. Peter's Basilica (Latin: Basilica Sancti Petri; Italian:Basilica Papale di San Pietro in Vaticano), is a Late Renaissance church located within Vatican City.
Designed principally by Donato Bramante, Michelangelo, Carlo Maderno and Gian Lorenzo Bernini, St. Peter's is the most renowned work of Renaissance architecture and remains one of the two largest churches in the world. While it is neither the mother church of the Catholic Church nor the Catholic Roman Rite cathedral of the Diocese of Rome, St. Peter's is regarded as one of the holiest Catholic shrines. It has been described as "holding a unique position in the Christian world" and as "the greatest of all churches of Christendom".
