History

Its history is long and fascinating, as it is believed to be the burial place of St. Peter, one of the apostles of Jesus Christ (the first Pope).

  • In the 4th century, Emperor Constantine ordered the construction of the original basilica on this site, completed around AD 349.
  • The original church underwent numerous renovations and transformations over the centuries. It became the centre of the Roman Catholic Church but showed signs of decline by the 15th century. By then, accommodating the increasing number of pilgrims was no longer deemed adequate.
  • During the 15th-century Renaissance, Rome saw a revival of interest in art, culture, and architecture. Popes such as Nicholas V and Julius II initiated various construction projects, including rebuilding St. Peter's Basilica, to match the significance of the Vatican.
  • In 1506, Pope Julius II entrusted architect Donato Bramante with creating a new plan for the basilica. Bramante envisioned an ambitious design that included demolishing the old basilica. He envisioned a colossal central dome surrounded by four arms. However, Bramante's plan was only partially realized due to financial constraints and the death of the Pope in 1513.
  • After Bramante's death, various architects continued the work, including Raphael and the younger Antonio da Sangallo. However, Michelangelo played a pivotal role in shaping the basilica. He redesigned the dome, making it more massive and harmonious with the rest of the building.
  • In the early 17th century, Carlo Maderno took over construction and expanded the nave to accommodate the growing number of pilgrims. Gian Lorenzo Bernini, the prominent Baroque architect and sculptor, contributed to the final appearance of the basilica by designing the impressive colonnade and the bronze baldacchin over the main altar.
Over the centuries, it underwent various restorations and renovations to preserve its structure and artistic and historical treasures.
