Religious affiliations: Of all citizens of the Hellenic Republic 97,6% are Greek Orthodox, 1,3% Muslim, 0,4% Roman Catholic, 0,1% Protestant, 0,6% other, including Jews. The Greek Orthodox Church is autocephalous, with its own Charter but indissolubly united in doctrine with the Great Church of Constantinople, i.e. the Ecumenical Patriarchate. On the peninsula of Chalkidiki, located in southeastern Macedonia, is the famous Mount Athos, where a number of monasteries of the Greek Orthodox Church form, as they have for centuries, an autonomous monastic community.
