Kea Hotels & AccommodationKea, also known as Gia or Tzia, Zea, and, in antiquity, Keos, is a Greek island in the Cyclades archipelago in the Aegean Sea. Its capital, Ioulis, is inland at a high altitude (like most ancient Cycladic settlements, for fear of pirates) and is considered quite picturesque. Other major villages of Kea are the port of Korissia and the fishing village of Vourkari.
