The Ecumenical Patriarchate looks like a large parish church, and the modesty was deliberate: under Ottoman rule no church could rise grander than a mosque. This small compound has been the seat of the Ecumenical Patriarch, first among equals of Orthodox bishops, since 1601. You step off a steep Fener lane into a hushed, gold-lit interior heavy with incense and dark wood. A wall of gilded icons faces you, pilgrims queue before glass reliquaries, and a carved patriarchal throne, said to be far older than the walls around it, stands beside the screen.
The Church of St. George at its heart burned and was rebuilt more than once, settling into its present form across the eighteenth and nineteenth centuries. Outside, the central gate stays sealed and painted black: Patriarch Gregory V was hanged from it on Easter Sunday 1821, at the start of the Greek War of Independence, and it has not been opened since. The Patriarchate is still a living seat. The small Greek Orthodox community of the surrounding quarter gathers here, and from these unassuming rooms the patriarch presides over a church of hundreds of millions.
