The Metropolis of Ancyra continued to be a residential see of the Eastern Orthodox Church until the 20th century , with about 40,000 faithful , mostly Turkish-speaking , but that situation ended as a result of the 1923 Convention Concerning the Exchange of Greek and Turkish Populations . The earlier Armenian Genocide put an end to the residential eparchy of Ancyra of the Armenian Catholic Church , which had been established in 1850 . It is also a titular metropolis of the Ecumenical Patriarchate of Constantinople . Both the Ancient Byzantine Metropolitan archbishopric and the ' modern ' Armenian eparchy are now listed by the Catholic Church as titular sees , with separate apostolic successions
