Vatican Necropolis

Beneath St. Peter's Basilica lies a Roman-era necropolis dating to the 1st-4th centuries AD, at the center of which a small 2nd-century shrine ("the Trophy of Gaius") was long venerated as marking the burial place of the Apostle Peter. Constantine chose to build the original St. Peter's Basilica directly over this shrine in the 4th century, despite the enormous engineering effort of leveling the hillside cemetery — a choice widely read as evidence of the site's early and firmly held significance to Roman Christians.

Archaeology

Systematic excavations were carried out beneath the basilica from 1940 to 1949 under Pope Pius XII's direction. In 1950 Pius XII announced that Peter's tomb had probably been found but that identifiable bones could not be confirmed. Further work led Pope Paul VI to announce in 1968 that bones recovered from a repository near the shrine — belonging to a robustly built male around 60-70 years old — were, in the Vatican investigators' judgment, likely Peter's. The identification remains debated among scholars, as the bones were moved between locations during the dig.
