How Tomb of Peter beneath St Peter's Basilica was found

Digging a tomb for Pius XI under the crypt, workers broke into a Roman street of mausoleums. Beneath the high altar the team found a small aedicula (the 'Trophy of Gaius' mentioned about 200 CE by the presbyter Gaius) built over a plain earth grave, surrounded by graffiti. Guarducci read a Greek scratch as ΠΕΤΡ[ΟΣ] ΕΝΙ, 'Peter is here,' and identified bones stored from a niche in the 'graffiti wall' as the apostle's.

What it is

A pagan-Christian cemetery on the Vatican hill with a small 2nd-century monument: two columns supporting a slab against a red-plastered wall, directly under the altars of the 4th-century and present basilicas. The 'graffiti wall' beside it bears dozens of Christian scratches with names of Peter and Messiah.

Why it matters for the Bible

The New Testament never says where Kefa (Peter) died, but 1 Clement and John 21:18–19 point to martyrdom, and Gaius of Rome (c. 200) said his 'trophy' was on the Vatican hill. The excavations found that trophy exactly where Constantine centred his basilica, proving that Christians honoured this spot as Peter's grave by the mid-2nd century. Whether the bones are his cannot be shown; Pius XII said so in 1950, and Paul VI's 1968 declaration remains a matter of faith, not archaeology.

Debated: The 2nd-century shrine and its location are accepted by most historians; the 'Petros eni' reading and the bones' identification are disputed, and the excavation methods were criticised.

The Hebrew word: kay-FAH

כֵּיפָא

כֵּיפָא is pronounced kay-FAH and means rock — Aramaic name given to Shimon by Yeshua (Greek Petros) (Strong's G2786 / G4074).
