In place of Kyriaki there used to be an ancient city named Flygonio, which means gushing water. This city allowed control of routes connecting the mountain settlements with coastal roads of Elikonas. The Macedionian Philippos V reputedly destroyed the city around 350 BC although it managed to survive as recently as the 6th century AD when an earthquake wiped it off the map. Only traces of the acropolis of Flygonio remain, mostly walls and foundations of some buildings. Nonetheless, those who want to travel to the past or are fans of archaeology will find the site interesting.
