This sanctuary lies on a sandstone cliff, and its origins date back to the 4th century AD, built by Basilian monks seeking a place to rest and pray. It is considered a privileged place of devotion and pilgrimage, given its importance for all Tropeans, not only for the cult of the Virgin of the Island. Accessing the Sanctuary is only possible via a flight of steps carved into the tufa rock. Its highest point also offers an extraordinary view of the sea and the beauty of the Coast. Inside the Sanctuary, there is a small museum housing artifacts found here over time.
