Diocese of Rome

Diocese of Rome

The Diocese of Rome is a Latin diocese of the Catholic Church 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 it has civil jurisdiction over Vatican City. The Diocese of Rome consists of two geographical jurisdictions: the Vicariate of Rome, and the small Vicariate of Vatican City. It is the metropolitan diocese of the Province of Rome, an ecclesiastical province in the Ecclesiastical Region of Lazio in Italy. According to Ca...

What it is

The Diocese of Rome is the Pope's own diocese: as Bishop of Rome, he heads it directly, making it the administrative seat of Catholicism worldwide. It isn't a single building to visit but a jurisdiction, and its historical and ceremonial center is the Archbasilica of St. John Lateran, the cathedral church of Rome and technically the pope's own cathedral, predating even St. Peter's Basilica in that role. Travellers come here for the Lateran complex itself — the basilica, its cloister, and the Lateran Baptistery — rather than for the diocese as an abstract entity.

Getting there

The Lateran complex sits southeast of the historic center, reachable by metro (Line A to San Giovanni) or a 20-30 minute walk from the Colosseum area.

Time to allow

Plan on one to two hours to see the basilica's interior, cloister, and baptistery without rushing.

When to go

Mornings tend to be quieter than midday, and the site draws fewer crowds than St. Peter's Basilica, though it can still fill up around religious feast days and Sunday services.

Combine it with

The area is easy to pair with other nearby sights: the Domus Aurea (1.1km) and Baths of Caracalla (1.3km) are both a short trip away, and the Arch of Constantine (1.4km) sits just beyond, close enough to fold into a single day exploring this stretch of Rome on foot.

The Archbasilica of Saint John Lateran, commonly known as the Lateran Basilica or Saint John Lateran, is the Catholic cathedral of the Diocese of Rome in the city of Rome, Italy.

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. D...
