What did excavations beneath St. Peter’s Basilica reveal about the possible tomb of St. Peter?

Excavations beneath St. Peter’s Basilica, which began in 1939, have not provided definitive evidence regarding the location of the apostle's tomb. While the emperor Constantine built a basilica on Vatican Hill, likely because he believed the relics of Peter rested beneath a small aedicula (shrine), modern archaeological findings remain inconclusive.1

The complexities of the site have led to divided scholarly opinions:

• The Aedicula: Some researchers argue that a box discovered in a later sidewall of the aedicula contains fragments of the apostle's remains, which may have originally been buried in the earth beneath the shrine.1
• Lack of Certainty: Many other scholars remain unconvinced by these findings. If a grave existed at the base of the aedicula, no identifiable traces of it remain today, and the contents of the box do not lead to a positive conclusion.1

Ultimately, archaeological investigation has not solved the question of the tomb's location with certainty; it remains possible that the grave was situated elsewhere in the vicinity or that the body was never recovered for burial.1
