Korissia, on Kea Island, echoes with a gritty history amid its rugged charm. It was one of the 4 autonomous cities of Kea State (Korissia, Ioulida, Poiisea, Karthaia), flourished mainly during the Archaic and Classical periods and was then absorbed by Ioulida and turned into its seaport. Due to its position it became an important center of transit trade during the Byzantine times, and during the Turkish occupation it became a permanent pirate hideout.

Today, in the settlement of Livadi, there are visible remains of an archaic temple probably dedicated to Sminthios Apollo and parts of the Acropolis wall.

Korissia on Kea Island is a charming blend of tradition and modernity. The historic port, while retaining its rough-hewn authenticity, now hosts vibrant cafes, tavernas, and shops that cater to both locals and visitors. The harbor bustles with life as fishing boats share space with yachts, reflecting the island’s evolving character.
