The Ierissos boat
Photo’s taken in may 2008. A different way to spend your time on Athos: Instead of trekking to different monasteries for a place to sleep, stay in one Monastery (in this case Vatopedi) and walk from there one day to Pantokratoros and the other day to Esfigmenou and so on.
Here you see a complete photoaccount.
The mobile office of the Holy Executive of the Holy Mountain. They issue your Diamoniterion (permit to stay) if you are on the list.
Apparently you can take the bus to Ierissos and get your Diamoniterion on the pier!

Athos - Agios Oros 
Regarding the drawing by Le Corbusier.. It looks a lot like the Acropolis in Athens, rather than any Mount Athos location I know.
Makis, I think you are right, I was thinking the same. I have asked the Le Corbusier foundation if they are sure this is an Athos location. Thanks.
