St. Peter’s Basilica: Difference between revisions

St. Peter's Basilica is a major papal basilica located in Vatican City, serving as one of the most important pilgrimage sites in the Catholic world. It is built over the traditional tomb of Saint Peter, the Apostle and first Bishop of Rome, and functions as a principal venue for papal liturgies and ceremonies, though it is not the cathedral of the Diocese of Rome (that distinction belongs to the Archbasilica of Saint John Lateran).<ref>According to the official basilica website (basilicasanpietro.va) and established historical records.</ref>

The current basilica, a masterpiece of Renaissance and Baroque architecture, was begun on **April 18, 1506**, under Pope Julius II to replace the 4th-century Constantinian basilica, and was solemnly dedicated on **November 18, 1626**, by Pope Urban VIII. Designed principally by Donato Bramante (initial Greek cross plan), Michelangelo (dome and unification), Carlo Maderno (Latin cross extension and façade), and Gian Lorenzo Bernini (furnishings, baldacchino, and colonnaded piazza), it represents the culmination of Renaissance architectural ideals and Baroque grandeur.<ref>Verified from Wikipedia and official sources on construction history.</ref>

The site of St. Peter's Basilica has been venerated since the 4th century, when Emperor Constantine built the original basilica over the believed burial place of Saint Peter (traditionally martyred in Nero's Circus c. 64–67 AD). Archaeological excavations in the 20th century confirmed a necropolis and tomb beneath the high altar.<ref>Excavations under Pope Pius XII (1939–1958); Vatican reports.</ref>

By the late 15th century, the old basilica was in disrepair. Pope Nicholas V began planning a new structure, but major work commenced under Pope Julius II in **1506**. The project evolved through multiple architects: Bramante's centralized plan, modifications by Raphael and others, Michelangelo's design of the dome (completed posthumously by Giacomo della Porta in 1590), Maderno's nave extension, and Bernini's Baroque embellishments (including the piazza, 1656–1667).<ref>Official basilica site and historical scholarship.</ref>
