This is a list of non-extant papal tombs, which includes tombs not included on the list of extant papal tombs. Information about these tombs is generally incomplete and uncertain.
Chronologically, the main locations of destroyed or unknown papal tombs have been: the obscure tombs of the first two centuries of popes near Saint Peter, the repeated waves of translations from the Catacombs of Rome, the demolition of the papal tombs in Old St. Peter's Basilica, and the 1306 and 1361 fires in the Archbasilica of Saint John Lateran.
Papal tombs have also been destroyed by other instances of fire, remodeling, and war (most recently, World War II). Others are unknown due to creative or geographically remote methods of martyrdom, or—in the case of Pope Clement I—both. Burial in churches outside the Aurelian Walls of Rome (Italian: fuori le Mura)—in the basilicas of Paul or Lorenzo—have not generally survived.
