Born Simon, a Galilean fisherman, Peter was renamed by Jesus and became the leader of the apostles — a role that, centuries later, made him the reason the Vatican exists at all.
Traditional roleLeader of the apostles, first Bishop of Rome
Traditional deathCrucified in Rome, c. AD 64–68, reportedly upside-down by his own request
Almost everything at the Vatican traces back to one man who never saw it built.
A fisherman called by name
The Gospels describe Jesus renaming Simon "Peter" (from the Greek petros, "rock"), naming him the foundation of the Church to come.
A complicated, human figure
The New Testament doesn't flatter him: he denies knowing Jesus three times before the crucifixion, then becomes, by tradition, the community's leader after the Resurrection.
Death in Rome
Early Christian writers place his martyrdom in Rome under Nero; tradition holds he asked to be crucified upside-down, considering himself unworthy to die as Jesus had.
Catholic tradition regards him as the first Bishop of Rome and, in that sense, the first pope — a title and structure that developed more fully in the centuries after his death.
Why was Simon renamed Peter?
According to the Gospels, Jesus gave him the name — meaning "rock" — declaring he would build his church on him, a moment central to why Peter's authority carried such weight afterward.
Did Peter ever set foot in the Vatican as it exists today?
No — Vatican City as a defined place didn't exist in his lifetime; he died on the same hillside centuries before it became the seat of the papacy.
