Start the tour with a visit to the cave where the Apostle John stayed during his exile and wrote the Book of Revelation. Continue to Hora (town) of Patmos built 3 km (1,8 mi) southwest of the harbor. It is many times been referred to as the queen of all Hora's, not only because of the Byzantine Monastery of the Apostle John the Evangelist, but for the Byzantine mansions that are unique to the island and said to be the strongest built in the Aegean.
