How Many Diocese Are There in Rome?

By Alice Nichols

Rome, known as the Eternal City, has a rich religious history that dates back to ancient times. As the capital of Italy and the center of Roman Catholicism, Rome holds great significance for followers of the faith. One important aspect of the Catholic Church in Rome is its hierarchical structure, which includes various dioceses.

What is a Diocese?
A diocese is an administrative division within the Catholic Church that comprises a specific geographical area. It is headed by a bishop who oversees the spiritual and administrative affairs of the diocese. The term “diocese” originated from the Greek word “dioikēsis,” meaning “administration.”

The Dioceses of Rome
In Rome, there are seven territorial dioceses known as suburbicarian dioceses. These dioceses are closely associated with the governance of the Roman Catholic Church and hold historical significance. Let’s explore each one in detail:

1. Diocese of Ostia

Located on Italy’s west coast, Ostia is home to one of Rome’s most ancient harbors. The Diocese of Ostia represents an honorary title given to the Dean of Cardinals, who presides over papal elections when there is a vacancy in the Holy See.

2. Diocese of Porto-Santa Rufina

The Diocese of Porto-Santa Rufina encompasses two towns near Rome: Porto and Santa Rufina. Historically, this diocese was responsible for supervising port activities in ancient Ostia and Tiber River navigation.
