Metropolis of Derkoi
The Metropolis of Derkoi () is a residential see of the Eastern Orthodox Church subject to the Ecumenical Patriarch of Constantinople and situated in the Istanbul suburb of Yesilköy (historically San Stefano). The cathedral is that of St. Parakevi in Therapia (Tarabya). The metropolitan is a member of the Patriarchal Synod. The present Metropolitan is Apostolos Daniilidis. History The village of Derkos/Derkoi (modern Durusu or Terkos) is attested since Classical Antiquity, but Emperor Anastasius I (r. 491–518) raised it to the status of a city and rebuilt it as a forward stronghold for the defence of Constantinople. Probably at the same time it was created as an episcopal see ("Bishopric of Derkoi and Chele", Επισκοπή Δέρκων και Χηλής). In the first half of the 6th century, the town and the see were known as a stronghold of the Monophysites. The Monophysite ascetic Zoora took refuge there after the Council of Constantinople (536). The see was a suffragan of the metropolis of Heraclea until the 10th century, when it became an autocephalous archbishopric. Bishop Gregory I took part in the Second Council of Nicaea in 787; Macarius I participated in the council of 879, Archbishop Constantine participated in the anti-Jacobite council
