Between Leros and Ikaria is the "ascetic shape" of Patmos called the Jerusalem of the Aegean due to overwhelming atmosphere of the island during the great celebrations of Christianity. Here, in one of Patmo's many caves, St. John the Theologian had a vision of the Apocalypse. An imposing monastery devoted to the saint domihates the heights above the picturesque houses and mansions which appear to be "hooked" to the roots of the monastery. The image the visitor will keep from Patmos will be completed by an excursion to its rocky coves and pleasant shores before passing over to the nearby islets of Fourni, Lypsi, and Agathoflissi.
