The town of Pythagoreio on the island of Samos is built on the ruins of the ancient nautical city and harbor. Formerly called Tigani, the town was renamed in 1955 to honor the locally-born mathematician Pythagoras. Here stands the most renowned archaeological collection of UNESCO World Heritage Sites named Pythagoreion.
The old city, Astypalea, is where the ancient Samos harbor, the oldest manmade port on the Mediterranean shore, and the Tunner of Eupalinos, a 1086-meter-long aqueduct, are located. The ruins of the Heraion of Samos, a colossal Ionic Era shrine dedicated to Goddess Hera, also stand here. Other notable attractions are the Panagia Spiliani Monastery, the Roman baths and the ancient amphitheater, and the town's fortification walls. The beach of Pythagoreia is also quite beautiful, with sand and pebbles leading into warm water. The 4.5 km beach is separated from Potokaki Beach by a small stream. A 250m strip is marked as a ‘Blue Flag’ beach, which means it has a high environmental standard. First settled sometime around the 4th millennium BC, this region has lived through the Neolithic times, the Trojan Era, the Hellenic Era, the Classical Period, the Ottoman Empire, and more.
