The remains of a watchtower from the Hellenistic era in Throni, not far from Methana, is one of those archeological finds that are only known to people who are very familiar with the area. First described by German archeologist Michael Deffner in 1912, the tower lies in a gorge northwest of Methana in a valley between two hills, above the little church of Saint George. The walls rise to almost 2 meters with a visible doorway. You can clearly see the four sides, each about 8 meters in length.
