These two traditional villages, situated in the Adelfi Forest, were established in the 16th century near the monastery and church of Virgin Mary Chrysokourdaliotissa (Kourdali). Like many villages in the region, they grew as they became refuges from constant invasions by conquerors: the Francs and later the Turks.
Expansion came via the narrow valley of Kourdali towards the village of Spilia, which derived its name from the Roman graves (spilioi in Greek) found in the area. Local asbestos mining was the main proficiency of the villagers for many years; thereafter they became skilled tailors and cobblers. Today, the villages’ cafes and craft shops are the main attraction.
