Some of the monks of Mt. Athos in the 11Cent. couldn't take the commotion, and moved off to central Greece and built their eyres where no one could possibly bother them. They climbed the cliffs and built their monasteries on top, bringing in supplies by hand, and then pulled the ladders up after they were done. Now you could only get in if they pulled you up in their baskets. Needless to say there are very few monks left now.
