Giacomo Barozzi da Vignola

Giacomo Barozzi da Vignola (1 October 1507 – 7 July 1573), known simply as Vignola, was a leading Italian architect of the 16th-century Mannerist period. He is best known for two major works: the Villa Farnese at Caprarola and the Church of the Gesù in Rome, the mother church of the Jesuits. Along with Serlio and Palladio, he helped spread the Italian Renaissance style across Western Europe, and he is often regarded as the most significant architect in Rome during the Mannerist era.

Born in the town of Vignola near Modena, he began his career in Bologna, supporting himself through painting and creating perspective templates for inlay craftsmen. In 1536 he first traveled to Rome to make measured drawings of Roman temples, planning to publish an illustrated edition of Vitruvius. From 1541 to 1543 he worked at Fontainebleau at the invitation of François I, where he likely met fellow Bolognese architect Sebastiano Serlio and the painter Primaticcio.

After returning to Italy, he designed the Palazzo Bocchi in Bologna before moving to Rome. There he worked for Pope Julius III and later for the Farnese papal family, collaborating with Michelangelo, whose style deeply influenced him. In 1558 he was in Piacenza to revise designs for the Palazzo Farnese, commissioned by Margaret of Austria, wife of Duke Ottavio Farnese and daughter of Emperor Charles V. From 1564 he continued Michelangelo’s work on St. Peter’s Basilica, constructing the two subordinate domes according to Michelangelo’s plans. He died in Rome in 1573, and his remains were reburied in the Pantheon in 1973.

His major architectural works include the project for the facade of the Basilica of San Petronio in Bologna (c. 1545); the Villa Giulia for Pope Julius III in Rome (1550–1553), where he worked with Ammanati under Vasari’s direction and the pope’s guidance; the Villa Farnese at Caprarola (1559–1573); the Villa Lante at Bagnaia (from 1566), including its gardens and water features; the Church of the Gesù in Rome; the Basilica of Santa Maria degli Angeli in Assisi (with Galeazzo Alessi); the Church of Sant’Andrea in Via Flaminia in Rome, notable for its oval dome; the Palazzo dei Banchi in Bologna; the Palazzo Farnese in Piacenza, a vast project only partially built; St. Peter’s Basilica, where he succeeded Michelangelo as chief architect; the Palazzo Contrari Boncompagni in Vignola; the facade of the Church of Santa Maria dell’Orto in Rome (1576–1578); the Orti Farnesiani on the Palatine in Rome; and the project for the Church of Sant’Anna dei Palafrenieri in Vatican City (c. 1570), with an oval dome set in a rectangle, later taken up by many Baroque architects.
