The Portaitissa, or Keeper of the Gate, icon is from the monastery of Iviron on Mt. Athos. This icon was placed inside one of the chapels in the monastery, but whenever the monks would wake up in the morning, the icon moved itself to the gate of the chapel. The mark on the right cheek of the Virgin Mary is from the knife of pirate who stabbed the icon. When he did this, the icon started bleeding. The pirate repented and became a Christian at that moment. He later became a saint of the church known as St. Barbarian, because in his humility, he didn't feel worthy enough to choose a higher name for himself.
