The Holy Monastery of Vatopedi on Mount Athos, Greece.

The Holy and Great Monastery of Vatopedi on Mount Athos, Greece, was built during the second half of the 10th century by three monks, Athanasius, Nicholas, and Antonius, from Adrianople, who were disciples of Athanasius the Athonite.
From then onwards, several buildings have been constructed, most of them were built during the Byzantine period and during the 18th and 19th centuries when the monastery reached its highest peak.
About 100 monks live in the monastery today, where extensive construction projects are underway to restore the larger buildings.

There are seven icons of the Mother of God in the monastery purported by believers to be miracle-working: Elaiovrytissa, Ktetorissa (Vimatarissa), Esphagmeni, Pantanassa, Pyrovolitheisa, Antiphonitria and Paramythia.
