Mount Athos (Greek: Όρος Άθως) is a mountain on the peninsula of the same name in Macedonia, northern Greece, called in Greek Άγιον Όρος (Agion Oros, transliterated often as Hagion Oros), or in English, "Holy Mountain". In Classical times, the peninsula was called Ακτή (Acte or Akte). Politically it is known in Greece as the Autonomous Monastic State of the Holy Mountain. This World Heritage Site is home to 20 Eastern Orthodox monasteries and forms a self-governed monastic state within the sovereignty of the Hellenic Republic. Spiritually, Mount Athos comes under the direct jurisdiction of the Ecumenical Patriarchate of Constantinople.
The peninsula, the easternmost "leg" of the larger Chalcidice peninsula, protrudes into the Aegean Sea for some 60 kilometres (37 mi) at a width between 7 to 12 km and covers an area of 335.637 square kilometres (129.59 sq mi), with the actual Mount Athos and its steep, densely forested slopes reaching up to 2,033 metres (6,670 ft). The seas around the end of the peninsula can be dangerous.
