The architectural and artistic history of St. Peter's Basilica: from its origins to the Renaissance and Baroque transformations that have shaped its present form of the center of Christianity. Through a great photographic campaign, the unrepeatable monumental complex of Saint Peter’s, sculpted by genius and faith. Symbol of the Catholic Church and the Eternal City, San Pietro is the desired place, imagined and built by the Popes of the Renaissance, with the help of the greatest artists of all time, such as Bramante, Michelangelo, Raffaello, Maderno and Bernini. With the help of reconstructive drawings, prints, engravings and great pictorial works, the most qualified scholars of the Late Antiquity, Middle Ages and Modern age, propose an extraordinary fresco of the life of the Basilica Petrina, commissioned by the Emperor Constantine and built on the ashes of one of the oldest buildings of worship of early Christianity, the place of martyrdom and burial of the Apostle Peter. The spectacular aerial photographs of the exterior and the shots of the interior show the current appearance of the building, with the Baroque monuments of the Popes and the huge mosaic surface that decorates it.
