The Holy Monastery of Saint Gregory , also known as Gregoriou Monastery is an Orthodox Christian monastery in the monastic state of Mount Athos in Greece. The Monastery ranks seventeenth in the hierarchy of the Athonite monasteries. It is built by the sea, on the southeastern side of the peninsula, neighboring the monasteries of Simonopetras and Dionysiou. Gregoriou is very much a pilgrim friendly monastery with a strong sense of pastoral care. Pilgrim visitors are high and well provided for. When visiting Gregoriou, one feels how the Monastery is completely girt by the sea, built on a corner of land jutting into the sea, with only steep craggy rocks backed up behind it.
