Hagia Triada Monastery

Church in Heybeliada

Perched above a picturesque line of poplar trees in a spot that has been occupied by a Greek monastery since Byzantine times, Hagia Triada is an 1844 complex that housed a Greek Orthodox theological school until 1971, when it was closed on the government's orders; the Ecumenical Orthodox Patriarchate is waging an ongoing campaign to have it reopened. There's a small church with an ornate altar and an internationally renowned library that houses many old and rare manuscripts.

To visit the library, you'll need to gain special permission from the abbot, Metropolitan Elpidophoros. A fayton will charge around ₺30 to bring you here from the centre of town.
