The archaeological site or fortress of ancient Zarakas is on the northern side of the Gerakas inlet right behind the village, where traces of prehistoric habitations have been found.
Still visible are parts of the ancient wall and sections of homes, probably dating from the Hellenistic and later periods.
According to Pausanias (1, 38, 4), the site was named after the hero Zarikas, son of Petraios, the king of Karystos and a friend of Apollo, who founded a town there between 1300 and 1200 BC
