Crete (Greek: Κρήτη; [kriti]) is the largest and most populous of the Greek islands, the fifth largest island in the Mediterranean Sea, and one of the thirteen administrative regions of Greece. It forms a significant part of the economy and cultural heritage of Greece while retaining its own local cultural traits (such as its own dialect, poetry, and music). Crete was the centre of the Minoan civilization (c. 2700–1420 BC), the earliest "high culture" civilization in Europe, which built the first palaces in Europe.
