At the south easternmost edge of Greek dominion, spreads out the calm beauty of Kastelorizo. Belying former grandeur the island of Megisti, as it is officially known even from ancient times, derives its name from the Greek word meaning "largest" because it happens to be the largest island in a picturesque cluster surrounding it. The total area of this "polynesia" (island complex) is 11.9 square Kms. It is a mountainous and rocky island. The colorful capital and port is built amphitheatrically around a windless bay on the north western coast.
Kastelorizo is (with the exception of the nearby islet of Stroggýli) the easternmost Greek island and is situated in the Eastern Mediterranean. It lies about 2 miles (3 km) from the Anatolian coastal town of Kaş, more or less half-way between Rhodes and Antalya. It is six kilometres long and three kilometres wide, with a surface of 9.2 km². It has a triangular shape, and is oriented from NE to SW. The island features three capes: Agios Stefanos (north), Nifti (east) and Pounenti (south west); between the first two there is a wide and accommodating bay, the island's main harbour, where one finds the only town on the island. Cape Agios Stefanos, the nearest to Anatolia, is 2250m south of the modern Turkish town of Kaş (Greek: Andífli, the Ancient Greek City of Antiphéllos). Cape Nifti lies some greater distance from the Anatolian coast. The island is mountainous, with high and steep coastlines, which become more difficult to access moving west. The soil is composed of limestone, and produces only small amounts of olives, grapes and beans. On the island there is no source of drinking water. The Municipality of Megísti includes the populated offshore islands of Ro (pop. 15) and Stroggýli (9) as well as several uninhabited islets. It has a total land area of 11.987 km².
