Mt. Athos—where no woman has ever set foot—is located on the easternmost of the three “fingers” that make up Greece’s stunning Halkidiki Peninsula. Greek Orthodox monks have made wine continually on Mt. Athos for more than one thousand years. Known in Greek as “Holy Mountain,” the wine region is home to twenty monasteries—there are no other residences—and some 1700 monks who live an ascetic, isolated life. Only men are allowed to reside there or visit. Indeed, to maintain its males only policy once Greece was admitted to the European Union, Mt. Athos had to be given a special exemption from the EU regulation stipulating the free movement of people across borders.
