# Suburbicarian diocese

The seven suburbicarian dioceses are Roman Catholic dioceses located in the vicinity of Rome, whose (titular) bishops are the (now six) ordinary members of the highest-ranking order of Cardinals, the Cardinal Bishops (to which the Cardinal-patriarchs were added).

## The seven suburbicarian sees

The suburbicarian dioceses have varied slightly over time and nowadays consist of:

The see of Ostia is conferred on the Dean of the College of Cardinals in addition to the see he already had. (Until 1914, the Dean received the see of Ostia and Velletri in place of the see he had earlier. The sees of Ostia and Velletri were separated in 1914.) The Cardinal-Dean used to be the longest-serving cardinal bishop, but is now chosen by the six cardinal bishops with the approval of the Pope.
