Next to the Holy Trinity Monastery of Saint Nektarios is the Monastery of Saint Katherine. Before the existence of the Monastery of Saint Katherine, there was a chapel dedicated to St. Katherine where an icon of this same Saint was miraculously discovered. In 1908 two nuns bought the chapel.

The first miracle of the Saint happened in 1924 when it was decided to dig a water well for the monastery. Thirty meters were dug but no water was found.

At that time a priest-monk from Mount Athos was visiting the Monastery and prayed to St. Katherine with the nuns. At the same time, he lowered the miraculous icon of St. Katherine down the dry well, censed the area, and prayed. That night, as the nuns were in prayer, a loud noise was heard and the small monastery shook at its foundations. In the morning the monk went down to the dry well to remove the icon, thinking that the Saint was angry that was left there in the dirt. However, on the walls of the dry well, he noticed a Cross stuck between the dirt and rocks. He noticed also that the bottom of the Cross was wet. As he was removing the icon he called to the nuns and proclaimed the miracle. This once-dry well has flowed abundantly ever since and has adequately served the needs of the Monastery.
