Carlo Maderno’s broad façade extended St. Peter’s Basilica and set a major early-1600s model for Roman church fronts. This highly visible project helped define the monumental scale that later Roman Baroque architects would expand and challenge across the city.
Pope Urban VIII commissioned Gian Lorenzo Bernini to design the Baldacchino, a monumental canopy over the papal altar and St. Peter’s tomb. It linked architecture and sculpture into a single dramatic centerpiece, a signature approach for Roman Baroque design.
Construction of Palazzo Barberini began as the Barberini family rose to power under Pope Urban VIII. Worked on by Carlo Maderno, Gian Lorenzo Bernini, and Francesco Borromini, the palace became a major showcase for Baroque residential planning and ceremonial spaces in Rome.
Pietro Bernini completed the boat-shaped Fontana della Barcaccia at the base of the future Spanish Steps. As a public fountain fed by the Acqua Vergine aqueduct, it shows how Baroque Rome used waterworks and sculpture to shape everyday urban experience.
Francesco Borromini’s small church, often called “San Carlino,” was dedicated in 1646 after construction began in 1638. Its inventive geometry and flowing interior surfaces became a turning point, showing a more experimental side of Roman Baroque design.
Sant’Ignazio was built as the church of the Jesuit Roman College, supporting preaching and education in the heart of Rome. Its large, clearly organized interior shows how Roman Baroque churches could combine grand scale with functional planning for crowds and ceremonies.
Bernini began Palazzo Montecitorio as a grand urban residence in 1650; construction later continued under Carlo Fontana. The long building campaign shows how major Roman palaces could evolve across decades, carrying Baroque ideas into the next generation of architects.
Commissioned by Pope Innocent X and designed by Bernini, the Fountain of the Four Rivers was built between 1648 and 1651. It turned the center of Piazza Navona into a theatrical stage, using water, an obelisk, and river figures to represent papal reach across the known continents.
Work began in 1652 to rebuild Sant’Agnese in Agone beside the Pamphili family palace, making the church part of a larger urban statement in Piazza Navona. The project involved major architects, and it shows how papal patronage linked family prestige, church building, and city planning.
Borromini’s church for the Sapienza (the University of Rome) combined complex geometry with a striking spiral lantern. Completed and consecrated in 1660, it strengthened the idea that Roman Baroque architecture could be intellectually ambitious while still serving public institutions.
Pope Alexander VII commissioned Bernini to shape St. Peter’s Square with an embracing oval colonnade. Built from 1656 to 1667, it organized movement and ceremonies on a massive scale and became one of the most influential Baroque urban designs in Europe.
Designed by Bernini for the Jesuit novitiate, Sant’Andrea al Quirinale was completed in 1670 after building began in 1658. Its focused, oval-centered plan shows a mature Baroque approach: guiding attention toward the altar using light, geometry, and controlled drama.
The Spanish Steps were built between 1723 and 1725 to connect two major levels of the city with a monumental public stairway. This project reflects late Baroque urban planning: turning circulation (how people move) into an architectural event that shaped a whole neighborhood.
Work began in 1732 on the Trevi Fountain, designed by Nicola Salvi, as a monumental endpoint for the Acqua Vergine aqueduct. Built into the façade of Palazzo Poli, it shows how late Roman Baroque design blended architecture, sculpture, and civic water supply into a single urban landmark.
Ferdinando Fuga completed the Palazzo della Consulta in 1737 for Pope Clement XII. Its restrained late-Baroque style points toward a more orderly, institutional architecture, showing how Roman building shifted from the high drama of the mid-1600s toward a more administrative cityscape.
Between 1730 and 1740, Ferdinando Fuga expanded and reshaped the Palazzo Corsini for the Corsini family, closely tied to Pope Clement XII. The project is a clear late-period outcome of Roman Baroque patronage: large-scale residences designed to project power, host collections, and organize city-facing façades.
The Trevi Fountain was finished in 1762, after Nicola Salvi’s death, by Giuseppe Pannini. Although slightly beyond 1750, its completion helps show the long tail of Roman Baroque urban projects—where decades of planning and building could still produce a unified public spectacle centered on water and stone.
