The monastic establishment was founded in the year 1990, in the immediate vicinity of the cave where it is believed that the Holy Apostle Andrew preached the Gospel.
It was discovered in 1918 by Jean Dinu, a lawyer. After dreaming one night, he came in this area to find the cave in an advanced state of degradation. After cleaning it of the vegetation inside, he built a couple of cells and the first monks came in a short time.
It was sanctified in 1943 by the bishop Chesarie Paunescu but during the communist period it was destroyed and turned into a shelter for animals.
