An impressive cliff with a flat peak stands out when you explore the area of Korthi. After driving past the village of Kochylou, you will reach the bottom of the steps that will lead you to the castle, where you will come across ruins of stone houses, underground reservoirs and the church of Faneromeni (Koimisi Theotokou – Assumption of Mary). From that point, you can also enjoy a unique view. The castle that was once called Epano Kastro or Palaiokastro dates back to the Middle Ages. An influential medieval city with 2-meter thick walls had been built at this location. Some sections of those walls are still there to be seen.
