Mount Athos (Greece) size comparison
336 km2 / 130 mile2
Mount Athos is a mountain and peninsula in northeastern Greece and an important centre of Eastern Orthodox monasticism. It is governed as an autonomous polity within the Hellenic Republic.
Although Mount Athos is legally part of the European Union like the rest of Greece, the Monastic State of the Holy Mountain and the Athonite institutions have a special jurisdiction which was reaffirmed during the admission of Greece to the European Community (precursor to the EU). This empowers the Monastic State’s authorities to regulate the free movement of people and goods in its territory; in particular, only males are allowed to enter.
