Mt. Athos in Greece is a unique place where Orthodox monks live a monastic life. Though Greece protects the peninsula, it is self governed by the monks of the 20 monasteries of the Eastern Orthodoxy. Special permission is needed to visit Mt. Athos and only a few visitors are allowed each month. Mt. Athos does not permit women to enter and this ban has been in place since 1045 CE, since the time of the Byzantine emperor Constantine Monomachos. Mt. Athos does not even permit female animals (female cats are allowed since they catch rats).
Most of us will never set foot in this autonomous monastic state where orthodoxy has been preserved for a millenia. So the next best option is to watch the CBS 60 Minutes feature on this. (Part 1, Part 2). Ironically, the CBS clips are sponsored by viagra.
