The missionary pre-diocesan jurisdiction is not part of any ecclesiastical province. It is under the direction of the Congregation for the Oriental Churches, an unusual structure for a Latin see, and directly dependent on the Holy See.
Its cathedral seat is the Marian Cathedral of the Annunciation in İskenderun (Alexandria). It has the Co-Cathedral of St. Anthony of Padua in Mersin as well.
History
Established originally on 13 March 1845 as the Apostolic Prefecture of Trabzon, named for its location on the Black Sea, not for any preceding jurisdiction.
Promoted on 30 November 1990 as the Apostolic Vicariate of Anatolia,[2] led by a titular bishop.
As of 2020, the vicariate, which covers 450k square kilometers, had six parishes and two missions to serve a thousand Turkish Christians as well as Christian refugees from Syria, Iraq, Iran, Afghanistan, and Pakistan.[3]
