The Vatican Hill South Edge forms the natural boundary of the city-state towards the Via Aurelia and the Tiber valley. This topographic edge is geologically characterized by steep tufa cliffs that have served as a natural defensive line since ancient times. Historically, this perimeter area was the site of the ancient Vatican gardens and lies in close proximity to the Circus of Nero, where tradition holds that Saint Peter was martyred. During the construction of the present St. Peter's Basilica in the 16th and 17th centuries, the south edge was urbanistically integrated through massive foundational engineering and the erection of Bernini's southern colonnades. The elevation above Rome's street level emphasizes the Vatican's unique enclave status and provides commanding views over the urban landscape. Today, this section is secured by high Vatican walls that rest upon medieval and Renaissance fortifications.
