The grave lies at the foot of the aedicula beneath the floor. The remains of four individuals and several farm animals were found in this grave. In 1953, after the initial archeological efforts had been completed, another set of bones were found that were said to have been removed without the archeologists' knowledge from a niche ("loculus") in the north side of a wall (the graffiti wall) that abuts the red wall on the right of the aedicula. Subsequent testing indicated that these were the bones of a 60- to 70-year-old man. Margherita Guarducci argued that these were the remains of Saint Peter and that they had been moved into a niche in the graffiti wall from the grave under the aedicula "at the time of Constantine, after the peace of the church" (313). Antonio Ferrua, the archaeologist who headed the excavation that uncovered what is known as Saint Peter's Tomb, said that he was not convinced that the bones that were found were those of Saint Peter.
