07 Jan St Peter’s Basilica: Renaissance Masterpiece at the Heart of the Vatican

Construction began under Pope Julius II in 1506, the building we see today was completed in the early 17th century, It served as the focal point for the Jubilee of 2025, whose public conclusion came with the closing of the Holy Door in early January 2026.

A short architectural history

The present St. Peter’s Basilica replaced Constantine’s fourth‑century church; construction of the new basilica began in 1506 under the commission of Pope Julius II, and a succession of master architects and artists shaped the project over more than a century. Donato Bramante produced the first major Renaissance plan, proposing a centralized Greek‑cross scheme; Michelangelo later took over the design and is credited with the basilica’s iconic dome; Carlo Maderno completed the extended nave and the façade in the early 1600s; Gian Lorenzo Bernini added the great Baroque colonnade that frames St. Peter’s Square.

Key dates and facts

Groundbreaking: 1506 (Pope Julius II).

Principal completion: early 17th century; the building was effectively finished and consecrated in the 1620s, with many sources citing 1626 as the completion year for the major works.

Plan and style: a synthesis of High Renaissance central‑plan ideals and later Baroque additions; the basilica is a three‑aisled Latin cross with a monumental dome above the crossing.

Dome: Michelangelo’s dome dominates Rome’s skyline and reaches a height that makes it one of the most celebrated domes of the Renaissance era.

Art, relics and spiritual role

St. Peter’s houses major works of art, papal tombs, and the traditional shrine of Saint Peter the Apostle beneath the high altar; it is one of the four major basilicas of Rome and a principal pilgrimage destination for Catholics worldwide. The building’s layered authorship—Bramante, Michelangelo, Maderno, Bernini—makes it a living catalogue of Renaissance and Baroque genius.World History Edu+1.

The Jubilee of 2025 and the closing of the Holy Door

The Jubilee of 2025 was opened by Pope Francis on Christmas Eve, 2024, and was celebrated as the “Jubilee of Hope.”  It attracted an estimated 33 million pilgrims to Rome and to St. Peter’s, where the basilica’s Holy Door served as a central symbol of the jubilee pilgrimage. The public rites marking the end of the jubilee took place last night with Pope Leo XIV proceeding to the door and kneeling in prayer.  After prayers, he then closed the bronze Holy Door, marking the formal conclusion of the Jubilee period. The closing ceremony at St. Peter’s was a liturgical and symbolic moment that signalled the end of the special Jubilee year and the large‑scale pilgrimage events associated with itBritannica. While a Pope can call an extraordinary jubilee year at any time, the next ordinary Jubilee would be in 2050.
