This is where Pythagoras and as legend has it, the goddess Hera were born. The island is filled with ruins, the largest being the Hereion, an extensive temple built by the tyrant Polycrates and dedicated to the goddess. Besides the Hereion, Polycrates ordered the construction of a 1,036 m tunnel to bring water inside the city. It was a remarkable work of engineering for that time. A large jetty on which stands a monument dedicated to the famous mathematicians Pythagoras, is located in the island city that carries its name, Pythagorio. Hop on a hydrofoil move to the Dodecanese island of Patmos, a small and charming island that was the exile place of St. John the Evangelist. Here, living in a cave, Saint John wrote the Book of the Apocalypse. From the islandís monasteries, perched on top of the hill, descend into the main town and harbor of the island, Skala.
