Cyclades

The Cyclades (; Greek: Κυκλάδες, romanized: Kykládes, IPA: [ciˈkla.ðes]) are an island group in the Aegean Sea, southeast of mainland Greece and a former administrative prefecture of Greece. They are one of the island groups which constitute the Aegean archipelago. The name (Κυκλάδες νήσοι, Kykládes nísoi, 'encircling islands') refers to the archipelago forming a circle around the sacred island of Delos. The largest island of the Cyclades is Naxos; the most populated, however, is Syros.
