Crete, Greece's largest island, is known for its varied terrain, which ranges from fine-sand beaches at Elafonisi to the White Mountains. Mt. Ida, the tallest of the range, is home to the Ideon Cave, which was the birthplace of Zeus, according to Greek mythology. Crete forms a significant part of the economy and cultural heritage of Greece, while retaining its own local cultural traits (such as its own poetry and music). It was once the center of the Minoan civilization (c. 2700-1420 BC), which is the earliest known civilization in Europe. The capital, Heraklion, is home to the renowned Heraklion Archaeological Museum, housing Minoan artifacts, and Knossos, a Bronze Age settlement. Crete is one of the most popular holiday destinations in Greece. Popular tourist attractions include the archaeological sites of the Minoan civilisation, the Venetian old city and port of Chania, the Venetian castle at Rethymno, the gorge of Samaria, the islands of Chrysi, Elafonisi, Gramvousa, Spinalonga and the Palm Beach of Vai, which is the largest natural palm forest in Europe.
