The Halki Seminary (Ruhban Okulu) on Heybeliada is one of the most significant — and most debated — sites in the Princes' Islands: the historic theological school of the Greek Orthodox world, closed for over half a century but perhaps on the cusp of reopening.
A school that shaped a church
Founded in 1844 within the Aya Triada monastery on Ümit Tepesi, Halki became the pre-eminent Greek Orthodox seminary — twelve Ecumenical Patriarchs, including the current Patriarch Bartholomew, studied here. It was closed in 1971 after a change in Turkish law placed private higher education under state control and the seminary declined to be nationalised.
Will it reopen?
The building has been restored (nearing completion in 2025–26) and a reopening has been discussed at the highest political level, with the 2026–27 academic year floated. Its teaching status was still unresolved as of late 2025 — the single most current "news" angle on the islands, so check the latest before you go.
Visiting
The grounds and chapel are usually open to visitors (reported daily except Sundays, free), while the library and upper floors are restricted. It's a steep walk or bike ride up from the Heybeliada pier; ask before photographing interiors.
