Half a day is enough Near the airport, south-east coast Open year-round

A small, whitewashed harbour town on Samos' south-east coast, named after its most famous son: Pythagoras, born here around 570 BC. Alongside the nearby Heraion, Pythagoreio's ancient port, fortifications and the remarkable Eupalinos Tunnel earned it UNESCO World Heritage status in 1992. Half a day covers the town itself — longer if you add the tunnel and temple nearby.

What to see

  • The harbour and Pythagoras statue — the iconic bronze figure of Pythagoras with his triangle, looking out over the water toward Turkey.
  • Lykourgos Logothetis Castle — a 19th-century fortress built over the ancient acropolis, with views across the strait.
  • The Eupalinos Tunnel — a short drive from the town centre; a 6th-century BC aqueduct tunnel dug through Mount Kastro from both ends, a genuine feat of ancient engineering.
  • The archaeological site and small museum — remains of the ancient city walls and harbour works, with finds displayed locally.

Yes — it's close to Samos International Airport, has the international ferry to Kusadasi, Turkey, and puts you within a short drive of the Heraion, the Eupalinos Tunnel and several east-coast beaches.
