Syrian Catholic Archeparchy of Mossul

The Syrian Catholic Archeparchy of Mosul is an Eastern Catholic church organization in Nineweh Province that oversees multiple parishes. Saint Thomas Cathedral serves as its administrative center and main church.

The organization was founded in 1790 and initially covered large territories until 1862, when part of its jurisdiction was transferred to the newly established Baghdad Archeparchy. This change set the modern structure and geographic scope of the institution.

The Archeparchy oversees communities following the Syriac Catholic tradition, an Eastern form of Catholicism with its own liturgies and practices. These communities trace their roots to the ancient church of Antioch and maintain a very old Christian lineage.

The site is located in Mosul, the largest city in Nineweh Province, near the historical city center. Visitors should know that this is an active place of worship and access may vary depending on service times and local conditions.

Saint Thomas Cathedral was fully restored after 2017 following heavy damage during the conflict. This reconstruction was an important step for the community to preserve its religious sites and continuity.
