attached at right angles, the so-called Graffiti Wall, named after the large number of Latin graffiti to be found there. During the excavations in the grave the mortal remains of the Apostle Peter were not found. There were, however, in a marble-lined hole of the graffiti wall, some human bones. The archaeologist Margherita Guarducci suggested that during the time of construction of the Constantinian basilica, the remains of the Apostle Peter were removed from his original grave and placed in the opening. The archaeologist pointed to inscriptions in the wall behind the pillar monument including the letters PETR… EN I, as the designation of Peter relics. Other archaeological sites in Rome also have similar graffiti, suggesting that therein is a commemoration (by Christians) to Peter and Paul as martyrs. On 26 June 1968, Pope Paul VI announced that following scientific study, the relics of Saint Peter had been identified convincingly. Guided tours Tours of the excavations can be arranged with the Excavations Office in advance; for conservation, the number of visitors is limited. The tour lasts about an hour.
