First Basilica of St. Peter was constructed by emperor Constantine. It stood for more than millennium until pope Julius II decided to demolish old (1506) and to construct the new Basilica. The work was confided to the leading architect of the time Donato Bramante. He managed to remove the old Basilica and to construct foundation of the new building. Later, work was carried on by: Raphael, Giuliano and Antonio da Sangallo, Michelangelo, Della Porta, Maderno, Fontana and Bernini. The work was completed in 1665, with the building of the Bernini's colonnade. The Basilica of St. Peter is the principal church of the Western Christendom and the biggest church in the world.
