Crete rests approximately 160 km (99 mi) south of the Greek mainland. It has an area of 8,336 km2 (3,219 sq mi) and a coastline of 1,046 km (650 mi). It bounds the southern border of the Aegean Sea, with the Sea of Crete (or North Cretan Sea) to the north and the Libyan Sea (or South Cretan Sea) to the south. Crete and a number of islands and islets that surround it constitute the Region of Crete (Greek: Περιφέρεια Κρήτης), which is the southernmost of the 13 top-level administrative units of Greece, and the fifth most populous of Greece's regions. Its capital and largest city is Heraklion, located on the north shore of the island. As of 2011, the region had a population of 623,065. The Dodecanese are located to the northeast of Crete, while the Cyclades are situated to the north, separated by the Sea of Crete. The Peloponnese is to the region's northwest.
