Construction and Architectural Marvel
It started being built in 1506 by Pope Julius II in place of a 4th-century basilica on the tomb of St. Peter. Bramante, Michelangelo, Bernini and others, covered a 120-year gap, between 1626, and incorporated Renaissance symmetry with Baroque drama. Michelangelo crowned his design with a dome which is 136.6 meters in height and it is the highest point in Rome, where one gets panoramic views of Rome through the lantern.
Pilgrims are enclosed by elliptical colonnades by Bernini, which form the arms of the Church, and surround the St. Peter Square. The bronze baldachin by Bernini above the papal altar and the Pieta sculpture by Michelangelo are some of the interior details that create a strong feeling of reverence. It is enhanced by mosaics and relics.

Devoted to Saint Peter, the martyr and first pope, it incorporates the remains of the saint under the high altar, which establishes the succession of the apostles. Popes have been crowned here and such great councils as Vatican II have been held here, making up the doctrine of 1.4 billion Catholics. It was consecrated in 1626, and this was the peak of High Renaissance.
Spiritual and Cultural Meaning
The basilica is the symbol of the elevation of faith, which makes the visitors small in front of the contemplation. Papal audiences, Jubilee pilgrimages, and Daily Masses encourage the worship of the community and the Holy Door is open every 25 years to gain an indulgence. Pieces of art such as the Transfiguration cartoons by Raphael have theological undertones.
