The Holy Monastery of St. Catherine in Aegina is located on the right side of the road that goes up to the Monastery of Holy Trinity, St. Nectarios. Tradition says that there was a small church of Saint Catherine there and miraculously her icon was found. It is said that this little church was owned by a very blasphemous person and that in 1908 it was bought by two nuns.

According to tradition, when that estate was bought, there was no water at all. So they dug 30 meters, but they could not find water. Then, a saintly monk prayed with the nuns and lowered the icon into the well and burned incense in the dry well.

In the evening during the prayer, a loud noise and strange banging was heard and the small monastery shook from its foundations. "The Saint got angry, they said, because we left her in the soil and she is destroying us". But in the morning when the monk went down to take out the image, he sees a Cross carved on the walls of the well. He then saw that the Cross was wet at the bottom. He then took the image out of the well and informed the nuns of the joyous event. The well was producing water! Since 1924, the water of the well has existed until today and adequately covers the needs of the Monastery of Saint Catherine. Saint Catherine has performed many miracles in the monastery which are recorded in a special book.
