The Armenian Catholic Archeparchy of Lviv is a former, non-Metropolitan archeparchy (Eastern Catholic archdiocese) of the Armenian Catholic Church sui iuris (Armenian Rite).
It is immediately dependent on the Armenian Catholic Patriarch of Cilicia, not part of his or any ecclesiastical province, and in Rome under the Congregation for the Oriental Churches.
Its former cathedral archiepiscopal see and a minor landmark of World Heritage, the Armenian Cathedral of the Assumption of Mary in Lviv has been turned into an Armenian Apostolic Church.
Established in 1630 as Archeparchy (Archdiocese) of Lviv (Curiate Italian Leopoli), on territory previously without Ordinary of the particular church sui iuris.
Therefore, its faithful are "also" pastorally served by the Armenian Catholic Ordinariate of Eastern Europe.
