According to an ancient tradition, Peter was crucified upon the hill of Janiculum, near the Vatican, where the Church of San Pietro in Montorio now stands, and the hole in which his cross stood is still shown to the trustful visitor. A more probable tradition makes the scene of execution the Vatican hill, where Nero’s circus was, and where the persecution took place. Baronius makes the whole ridge on the right bank of the Tiber one hill, and thus reconciles the two traditions. In the fourth century the remains of Peter were transferred from the Catacombs of San Sebastiano (where they are said to have been interred in 258 a.d.) to the Basilica of St. Peter, which occupied the sight of the present basilica on the Vatican.
