Chalki (Halki, Khalki; Greek: Χ?λκη) is a Greek island in Dodecanese archipelago in the Aegean Sea, some 6 km west or Rhodes. With the area of 28 km' ² (11 sq. mi.), it is the smallest inhabited island of Dodecanese. It has permanent population of 330 (much increased during the summer months), concentrated in the only village Emborio. The community is divided in two parts, Chorio and the port. The island supported a much larger population but following emigration in the mid twentieth century Chorio was almost completely abandoned. A ruined medieval castle of the Knights of St. John overlooks the old town and the chapel contains some of the original frescoes.
