Basilica di San Pietro and its vast Renaissance dome

Basilica di San Pietro in Vatikanstadt gathers Renaissance design, Baroque sculpture and a vast dome above Saint Peter’s tomb—

Basilica di San Pietro rises at the centre of Vatikanstadt as a vast meeting of Renaissance architecture and Baroque art. Its dome, begun under Michelangelo and completed by Giacomo della Porta, gives the church its most recognisable interior and exterior feature.

A dome shaped by several Renaissance masters

The present basilica began on 18 April 1506, when Pope Julius II laid its foundation stone. The building was completed in 1626, after more than a century of changing plans, architects and patrons.

Donato Bramante supplied the first major design, while Raphael, Antonio da Sangallo the Younger, Michelangelo Buonarroti and Carlo Maderno each contributed to the building’s development. The church therefore records several phases of Renaissance architecture rather than a single author’s style. Its history and principal designers are set out in the basilica’s historical account.

From Bramante’s plan to Maderno’s façade

Bramante’s early concept used a centralised plan with a major dome above the crossing. Michelangelo revised the central structure and developed the dome, whose drum and rising profile dominate the skyline around Piazza San Pietro.

Giacomo della Porta and Domenico Fontana brought the dome to completion between 1588 and 1590. Carlo Maderno extended the building with a long nave and designed the broad façade facing the piazza. The result combines a central Renaissance core with the longitudinal arrangement associated with a Latin-cross church.

Bernini’s piazza, altar and sacred interior

Basilica di San Pietro stands above the traditional burial place of Saint Peter, the apostle whose name the church carries. The high altar sits beneath the dome, while the interior contains chapels, tombs, sculpture, mosaics and architectural monuments.

Gian Lorenzo Bernini shaped the relationship between the basilica and Piazza San Pietro. His colonnade forms a sweeping boundary around the open space, and his Baldacchino rises above the papal altar inside. The basilica and its setting belong to the Vatican City World Heritage property, which identifies the building as the work of Bramante, Raphael, Michelangelo, Bernini and Maderno.Vatican City World Heritage
