The Monastery of Saint John the Theologian (Greek: Μονή Αγίου Ιωάννου του Θεολόγου), commonly known as the Pelekete monastery (Turkish: Pelekete manastırı; Greek: Moνή Πελεκητής), is a ruined Byzantine-era monastery near modern Tirilye in Turkey (medieval Trigleia in Bithynia).
Its common name, "Pelekete", means "hewn with an axe" in Greek, and refers to its location on a steep rock.
[1] The monastery was a centre of iconodule opposition to Byzantine Iconoclasm, and in 763/4, it was attacked and burned down by the fanatically iconoclast governor Michael Lachanodrakon.
Lachanodrakon tortured the monastery's hegoumenos, Theosteriktos, and other monks, 38 of whom were buried alive at Ephesus.
[1] Locals today call it Aya Yani or Ayani, a corrupted form of its Greek name, meaning "Saint John".
