Pope Callixtus I, also called Callistus I, was the bishop of Rome from c. 218 to his death c. 222 or 223. He lived during the reigns of the Roman emperors Elagabalus and Alexander Severus. Eusebius and the Liberian catalogue list his episcopate as having lasted five years (217–222). In 217, when Callixtus followed Zephyrinus as Bishop of Rome, he started to admit into the Church converts from sects or schisms. He was martyred for his Christian faith and is venerated as a saint by the Catholic Church.
Pope Urban I (175?–230) was the bishop of Rome from 222 to 23 May 230. He was born in Rome and succeeded Callixtus I, who had been martyred. It was previously believed for centuries that Urban I was also martyred. However, recent historical discoveries now lead scholars to believe that he died of natural causes.
The Papal Basilica of Saint Peter in the Vatican, or simply Saint Peter's Basilica, is a church built in the Renaissance style located in Vatican City, the papal enclave that is within the city of Rome, Italy. It was initially planned by Pope Nicholas V and then Pope Julius II to replace the aging Old St. Peter's Basilica, which was built in the fourth century by Roman emperor Constantine the Great. Construction of the present basilica began on 18 April 1506 and was completed on 18 November 1626.
The Catacombs of Rome are ancient catacombs, underground burial places in and around Rome, of which there are at least forty, some rediscovered only in recent decades. Though most famous for Christian burials, either in separate catacombs or mixed together, Jews and also adherents of a variety of pagan Roman religions were buried in catacombs, beginning in the 2nd century AD, occasioned by the ancient Roman ban on burials within a city, and also as a response to overcrowding and shortage of land. The most extensive and perhaps the best known is the Christian Catacomb of Callixtus located near the Park of the Caffarella, but there are other sites, both Christian and not, scattered around the city, some of which are now engulfed by modern urban sprawl.
The Archbasilica Cathedral of the Most Holy Savior and of Saints John the Baptist and John the Evangelist in the Lateran, also known as the Papal Archbasilica of Saint John [in] Lateran, Saint John Lateran, or the Lateran Basilica, is the Catholic cathedral church of the Diocese of Rome in the city of Rome, and serves as the seat of the bishop of Rome, the pope. The archbasilica lies outside of Vatican City proper, which is located approximately 4 kilometres (2.5 mi) to the northwest. Nevertheless, as properties of the Holy See, the archbasilica and its adjoining edifices enjoy an extraterritorial status from Italy, pursuant to the terms of the Lateran Treaty of 1929. Laterano (Lateran) comes from an ancient Roman family (gens), whose palace (domus) grounds occupied the site; the Lateran Palace was the primary residence of the pope until the Middle Ages.
The Papal Basilica of Saint Paul Outside the Walls, commonly known as Saint Paul's Outside the Walls, is one of Rome's four major papal basilicas, along with the basilicas of Saint John in the Lateran, Saint Peter's, and Saint Mary Major, as well as one of the Seven Pilgrim Churches of Rome.
Saint Peter's tomb is a site under St. Peter's Basilica that includes several graves and a structure said by Vatican authorities to have been built to memorialize the location of Saint Peter's grave. St. Peter's tomb is alleged near the west end of a complex of mausoleums, the Vatican Necropolis, that date between about AD 130 and AD 300. The complex was partially torn down and filled with earth to provide a foundation for the building of the first St. Peter's Basilica during the reign of Constantine I in about AD 330. Though many bones have been found at the site of the 2nd-century shrine, as the result of two campaigns of archaeological excavation, Pope Pius XII stated in December 1950 that none could be confirmed to be Saint Peter's with absolute certainty. Following the discovery of bones that had been transferred from a second tomb under the monument, on June 26, 1968, Pope Paul VI said that the relics of Saint Peter had been identified in a manner considered convincing. Only circumstantial evidence was provided to support the claim.
The Lateran Palace, formally the Apostolic Palace of the Lateran, is an ancient palace of the Roman Empire and later the main papal residence in southeast Rome.
Papal inauguration is a liturgical service of the Catholic Church within Mass celebrated in the Roman Rite but with elements of Byzantine Rite for the ecclesiastical investiture of a pope. Since the inauguration of Pope John Paul I, it has not included the 820-year-old (1143–1963) papal coronation ceremony.
Old St. Peter's Basilica was the building that stood, from the 4th to 16th centuries, where the new St. Peter's Basilica stands today in Vatican City. Construction of the basilica, built over the historical site of the Circus of Nero, began during the reign of Emperor Constantine I. The name "old St. Peter's Basilica" has been used since the construction of the current basilica to distinguish the two buildings.
The Catacomb of Priscilla is an archaeological site on the Via Salaria in Rome, Italy, situated in what was a quarry in Roman times. This quarry was used for Christian burials from the late 2nd century through the 4th century. This catacomb, according to tradition, is named after the wife of the Consul Manius Acilius Glabrio; he is said to have become a Christian and was killed on the orders of Domitian. Some of the walls and ceilings display fine decorations illustrating Biblical scenes.
The papal tombs in old St. Peter's Basilica were the final resting places of the popes, most of which dated from the fifth to sixteenth centuries. The majority of these tombs were destroyed during the sixteenth through seventeenth century demolition of old St. Peter's Basilica, except for one which was destroyed during the Saracen Sack of the church in 846. The remainder were transferred in part to new St. Peter's Basilica, which stands on the site of the original basilica, and a handful of other churches of Rome.

The Catacombs of San Sebastiano are a hypogeum cemetery in Rome (Italy), rising along Via Appia Antica, in the Ardeatino Quarter. They are one of the very few Christian burial places that have always been accessible. The first of the former four floors is now almost completely destroyed.
In the Catholic Church, a basilica is a designation given by the Pope to a church building, conferring special privileges. Basilicas are distinguished for ceremonial purposes from other churches. The building need not be a basilica in the architectural sense. Basilicas are either major basilicas – of which there are four, all in the Diocese of Rome – or minor basilicas, of which there were 1,810 worldwide as of 2019.
Papacy in early Christianity was the period in papal history between 30 A.D., when according to Catholic doctrine, St. Peter effectively assumed his pastoral role as the Visible Head of the Church, until the pontificate of St. Miltiades, in 313, when Peace in the Church began.
