While Saint Paul the Apostle was traveling through Greece in year 63 to spread the Gospel of Christianity, he sent several of his followers to the island of Lefkada. One of these followers was Sosion, who Paul ordained as the first Bishop of Lefkada. When Sosion arrived at Lefkada, he visited a pine-forested hill in the area of Frini that was the site of a ruined ancient temple dedicated to Artemis. It was here that he and two priests decided to build a small church dedicated to the Virgin Mary.

The site became a Ceonobic Monastery and expanded in 1634. In 1734 while under Venetian rule, the monastery grew once more. The monastery suffered tragedy in 1886-1887 when it was caught in the blaze of a forest fire on the island. It was reconstructed to its previous state, and continued to serve the community until 1948. That year, a massive earthquake struck the island and the monastery once again caught fire. It subsequently fell into disrepair.

When Abbott Nikephoros (the current Abbott) took over in the 1980s, he and several others spent decades renovating the property until it was again suitable for visitors. Together they rehabilitated the garden and constructed a large courtyard complete with a small zoo. They also added a library, chapel (dedicated to St. Silouan the Athonite, one of Sosion’s priests), multiple guestrooms, a small nautical museum, and a larger three-floor Ecclesiastical museum exhibiting rare icons and manuscripts. There are even relics that belonged to St. Arsenius of Cappadocia, St. Silouan the Athonite, and St. Macrina the Younger just to name a few.
