Via Giulia

The road, committed by Pope Julius II to Donato Bramante, was one of the first important urban planning projects in papal Rome, and its opening had three aims: the creation of a major roadway inserted in a new system of streets superimposed on the maze of alleys of medieval Rome; the construction of a large avenue surrounded by sumptuous buildings to testify to the renewed grandeur of the Catholic Church; and finally, the foundation of a new administrative and banking centre near the Vatican, the seat of the popes, and far from the traditional city centre on the Capitoline Hill, dominated by the Roman baronial families opposed to the pontiffs.

Despite the interruption of the project due to the pax romana of 1511 and the death of the pope two years later, the new road immediately became one of the main centres of the Renaissance in Rome. Many palaces and churches were built by the most important architects of the time, such as Raffaello Sanzio and Antonio da Sangallo the Younger, who often chose to move into the street. They were joined by several noble families, while European nations and Italian city-states chose to build their churches in the street or in the immediate vicinity.
