The diocese of Presidio (Latin: Dioecesis Praesidiensis) is a suppressed and titular see of the Catholic Church. [1]
Presidium, identifiable with ruins at Henchir-Somâa in present-day Tunisia, is an ancient episcopal seat of the Roman province of Byzacena. [2]
There are two bishops known from this diocese. [3] [4]
Today, Presidio survives as a titular see; the current titular bishop is Roger William Gries, former auxiliary bishop of Cleveland.
