Tzia

Tzia, commonly known as Kea in English, is a Greek island in the Cyclades group in the Aegean Sea. The two names are used in reference to the same landmass, with Kea being the standard English name and Κέα the Greek name. The island lies in the northern Cyclades and is part of the South Aegean region, within the regional unit of Kea-Kythnos.

Geography and nature

Tzia is a rugged, hilly island with a coastline characterized by numerous coves and beaches. It supports olive groves, vineyards and small villages set among its rocky terrain. The interior remains relatively undeveloped, preserving a traditional Cycladic landscape.

Population and economy

The permanent population numbers in the low thousands and increases seasonally with tourism. The economy relies mainly on tourism, complemented by agriculture (notably olive oil and wine) and fishing. The island’s hospitality sector includes guest houses, small hotels and tavernas, especially active in the summer months.

History and culture

Kea has a long antiquity, with evidence of settlement dating to ancient Greece and earlier civilizations. The island’s principal ancient site, Karthea, lies on the western coast and includes remains of fortifications and public buildings. The Archaeological Museum of Kea is located in Ioulida (Ioulis), the island’s hilltop capital, which preserves a mix of traditional architecture and historic charm.

Principal towns and sites

Ioulida (Ioulis) is the main town, perched above the coast and known for its narrow streets and views. Korissia (Gialiskari) serves as the harbor and gateway for ferries. Notable beaches include Koundouros and Gialiskari, popular with locals and visitors alike.
