walk to the city wall of Pythagorion on Samos

walk to the city wall of Pythagorion:
when you start from Pythagorion to climb the mountain you pass first Moni Spiliani, a convent with a church in a cave. When you climb further uphill you reach after a strenuous stroll the old city walls of Pythagorion, which date from the times of Polycrates, the dictator who ruled over Samos in the times of Pythagoras.
