According to tradition and historical accounts, it is believed that St. John, one of Jesus' disciples, took Mary, the mother of Jesus, to Turkey. The earliest hints of this tradition come from writings by Irenaeus and Eusebius of Caesarea, which suggest that John came to Ephesus in Turkey and brought Mary with him. They believe they lived in Ephesus until Mary's Assumption (according to Catholic doctrine) or Dormition (according to Orthodox beliefs).
