On the island of Andros, visitors can explore five monasteries, including the oldest monastery in the Aegean Sea: the Holy Monastery of Panachrantos and Saint Panteleimon.
Perched at an altitude of 600 meters on the northern slopes of Mount Gerakones, the monastery stands proudly like a fortress, having overlooked the island since 961 AD. It was founded by Nikephoros Phokas upon his return from the Byzantine campaign against the Arabs in Crete.
