Given their (understandable) aversion to journalism and video cameras I haven’t found much documentary wise of quality regarding the Holy Mountain of Mount Athos. There was a US 60 minutes documentary a while back (see here) but this one runs for nearly an hour and gives some insight into life there; although focusing much on the “art and sculpture” at times. Tripped over while on a YouTube hunt for someone. One day, I might get myself there.
Enjoy – “Mount Athos – The Holy Mountain”
