Sestos or Sestus was an ancient Greek town of the Thracian Chersonese, the modern Gallipoli peninsula in European Turkey. Situated on the Hellespont opposite Abydos, it was the home of Hero in the legend of Hero and Leander, where according to legend she lived in a tower overlooking the sea. Sestos was an Aeolian colony, as it was founded by settlers from Lesbos. The ruins of the town are near to the modern settlement of Eceabat.
