Byzantine Iconoclasm
The Monastery of Saint Sergios of Medikion (), commonly simply known as the Medikion monastery (Μονή Μηδικίου; ), and later as the Monastery of the Holy Fathers () is a ruined Byzantine-era monastery near modern Tirilye in Turkey (medieval Trigleia in Bithynia). It is best known for the role its founders played in opposing Byzantine Iconoclasm.
