Mount Olympus (Greek: Όλυμπος ; also transliterated as Ólympos, and on Greek maps, Óros Ólimbos) is the highest mountain in Greece, located on the border between Thessaly and Macedonia, about 100 kilometres (62 mi) away from Thessaloniki, Greece's second largest city. Mount Olympus has 52 peaks. The highest peak Mýtikas, meaning "nose", rises to 2,917 metres (9,570 ft). It is one of the highest peaks in Europe in terms of topographic prominence.
Mount Olympus is noted for its very rich flora with several endemic species. It is a National Park of Greece and a World's Biosphere Reserve.
In Greek mythology Olympus was regarded as the "home" of the Twelve Olympian gods of the ancient Greek world. Hephaestus had built a palace inhabited by the gods. Olympus was not shaken by winds nor ever wet with rain, nor did snow fall upon it, but the airis outspread clear and cloudless, and over it hovered a radiant whiteness.
