The domed octagonal Lateran Baptistery (Italian: Battistero lateranense) stands somewhat apart from the Archbasilica of Saint John Lateran, Rome, to which it has become joined by later construction. This baptistery was founded by Pope Sixtus III in 440, perhaps on an earlier structure, for a legend grew up that Constantine the Great had been baptized there and enriched the structure. However, it is more likely that if he was baptized it was in the Eastern part of the Roman Empire and possibly by an Arian bishop. This baptistry was for many generations the only baptistery in Rome, and its octagonal structure, centered upon the large octagonal basin for full immersions, provided a model for others throughout Italy, and even an iconic motif of illuminated manuscripts, "The fountain of Life". Around the central area, where is the basin of the font, an octagon is formed by eight porphyry columns, with marble Corinthian capitals and entablature of classical form. On the ceiling of the Baptistry is the story of the Battle of the Milvian Bridge (312 AD). An ambulatory surrounds the font and outer walls form a larger octagon. Attached to one side, towards the Lateran Basilica, is a fine porch with two porphyry columns and richly carved capitals, bases and entablatures. The Baptistery was subject to an elaborate restoration during the pontificate of Pope Urban VIII. While its interior architecture was consolidated and embellished after plans of Gian Lorenzo Bernini, a fresco cycle with scenes from the life of Constantine was added by Andrea Sacchi on the walls of the ambulatory. In the meantime the early Christian liturgy of Easter baptisms was reanimated by the Baroque popes, baptizing adult "turchi ed ebrei" ("Turks and Jews") in a public ceremony on Easter eve. Its plain brick exterior was later on embellished with a frieze designed by Francesco Borromini in 1657, incorporating the arms of Pope Alexander VII.

Santi Marcellino e Pietro al Laterano is a Roman catholic parish and titular church in Rome on the Via Merulana. It is dedicated to Saints Marcellinus and Peter, 4th century Roman martyrs, whose relics were brought here in 1256.

Antonii Patavini de Urbe) is a Roman Catholic titular church in Rome on Via Merulana, one block from the Obelisk of St. John Lateran. It was built for the Order of Friars Minor, who needed a new home after they were moved from Santa Maria in Ara Coeli to allow the construction of the Victor Emmanuel II Monument. The church was consecrated on 4 December 1887 and was elevated to minor basilica status in 1931.On 12 March 1960 Pope John XXIII made it a titular church as a seat for cardinals. The most recent cardinal priest of the Titulus Sancti Antonii Patavini de Urbe was Cláudio Hummes.

Via Merulana is a street in the Rione Monti of Rome, Italy. It is south of the main train station (Stazioni Termini) of Rome, near the Oppian Hill. The street connects two major papal basilicas: the Santa Maria Maggiore to the St John Lateran. The name derives from family that owned the land during the medieval period. The present street was initiated by Pope Gregory XIII in the late 16th century and finished not long after by Pope Sixtus V. On the route described above are the facades of the church of Sant'Antonio da Padova and the adjacent Franciscan convent. Previously the site was occupied by the Villa Giustiniani Massimo. At the intersection with the Roman Via Labicana is the facade of the ancient church of Santi Marcellino e Pietro al Laterano. On the intersection with via di San Vito is the church of Sant'Alfonso di Liguori all'Esquilino of the Order of the Redemptorist Priests. Instead, on the intersection with via Mecenate is the Auditorium of Maecenas, a nymphaeum part of the Gardens of Maecenas. Other institutions on the route include the Museo Nazionale d'Arte Orientale and the Pontifical University Antonianum. The ancient church of San Matteo in Via Merulana was destroyed in 1810. The street is included in the crime novel That Awful Mess on Via Merulana by the Italian writer Carlo Emilio Gadda.

The Vatican Historical Museum (Italian: Museo storico vaticano) is one of the sections of the Vatican Museums. It was founded in 1973 at the behest of Pope Paul VI, and was initially hosted in environments under the Square Garden. In 1987 it was moved to the main floor of the Apostolic Palace of the Lateran and opened in March 1991. The Vatican Historical Museum has a unique collection of portraits of the Popes from the sixteenth century to date, the memorable items of the Papal Military Corps of the 16–17th centuries and old religious paraphernalia related to rituals of the papacy. Also on display on the lower floor are the papamobili (Popemobiles); carriages and motorcars of Popes and Cardinals, including the first cars used by Popes.

The Lateran Palace (Latin: Palatium Lateranense), formally the Apostolic Palace of the Lateran (Latin: Palatium Apostolicum Lateranense), is an ancient palace of the Roman Empire and later the main papal residence in southeast Rome. Located on St. John's Square in Lateran on the Caelian Hill, the palace is adjacent to the Archbasilica of Saint John Lateran, the cathedral church of Rome. From the fourth century, the palace was the principal residence of the popes, and continued so for about a thousand years until the Apostolic Residence ultimately moved to the Vatican. The palace is now used by the Vatican Historical Museum, which illustrates the history of the Papal States. The palace also houses the offices of the Vicariate of Rome, as well as the residential apartments of the Cardinal Vicar, the pope's delegate for the daily administration of the diocese. Until 1970, the palace was also home to the important collections of the Lateran Museum, now dispersed among other parts of the Vatican Museums. Following the Lateran Treaty of 1929, the palace and adjoining basilica are extraterritorial properties of the Holy See.

The Diocese of Rome (Latin: Dioecesis Urbis seu Romana; Italian: Diocesi di Roma) is the ecclesiastical district under the direct jurisdiction of the Pope, who is Bishop of Rome and hence the supreme pontiff and head of the worldwide Catholic Church. As the Holy See, the papacy is a sovereign entity with diplomatic relations, and civil jurisdiction over the Vatican City State located geographically within Rome. The Diocese of Rome is the metropolitan diocese of the Province of Rome, an ecclesiastical province in Italy. The first bishop of Rome was Saint Peter in the first century. The incumbent since 13 March 2013 is Pope Francis. Historically, many Rome-born men, as well as others born elsewhere on the Italian Peninsula have served as bishops of Rome. Since 1900, however, there has been only one Rome-born bishop of Rome, Pius XII (1939–1958). In addition, throughout history non-Italians have served as bishops of Rome, beginning with the first of them according to Catholic tradition, Saint Peter. It is the metropolitan archdiocese of the Roman ecclesiastical province and primatial see of Italy. The cathedral is the Archbasilica of Saint John Lateran. The primate of Italy is the pope, holding primacy of honor over the Italian sees and also primacy of jurisdiction over all other episcopal sees by Catholic tradition.

The Archbasilica Cathedral of the Most Holy Savior and of Saints John the Baptist and John the Evangelist in the Lateran (Italian: Arcibasilica del Santissimo Salvatore e dei Santi Giovanni Battista ed Evangelista in Laterano), also known as the Papal Archbasilica of Saint John [in] Lateran, Saint John Lateran, or the Lateran Basilica, is a 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.The church is the oldest and highest ranking of the four major papal basilicas as well as one of the Seven Pilgrim Churches of Rome, holding the unique title of "archbasilica". Founded in 324, it is the oldest public church in the city of Rome, and the oldest basilica of the Western world. It houses the cathedra of the Roman bishop, and has the title of ecumenical mother church of the Catholic faithful. The building deteriorated during the Middle Ages and was badly damaged by two fires in the 14th century. It was rebuilt in the late 16th century during the reign of Pope Sixtus V. The new structure's interior was renovated in the late 17th century, and its façade was completed in 1735 under Pope Clement XII. The current rector is Cardinal Archpriest Angelo De Donatis, Vicar General for the Diocese of Rome. The President of the French Republic, currently Emmanuel Macron, is ex officio the "First and Only Honorary Canon" of the archbasilica, a title that the heads of state of France have possessed since King Henry IV. The large Latin inscription on the façade reads: Clemens XII Pont Max Anno V Christo Salvatori In Hon SS Ioan Bapt et Evang. This abbreviated inscription translates as: "Pope Clement XII, in the fifth year [of his Pontificate, dedicated this building] to Christ the Savior, in honor of Saints John the Baptist and [John] the Evangelist". The inscription indicates, with its full title (see below), that the archbasilica was originally dedicated to Christ the Savior and, centuries later, co-dedicated to Saint John the Baptist and Saint John the Evangelist. Christ the Savior remains its primary dedication, and its titular feast day is 6 August, the Transfiguration of Christ. As the cathedral of the pope as bishop of Rome, it ranks superior to all other churches of the Catholic Church, including Saint Peter's Basilica.
